iii Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT 1.0 Introduction
The Surface Water Improvement and Management (SWIM) plan for the Pensacola Bay system is intended to provide a framework for resource management, protection, and restoration using a watershed approach. The SWIM Program is administered through the Northwest Florida Water Management District (NWFWMD or District) and includes management actions to address water quality, natural systems, and watershed functions and benefits. This plan is an update to the original plan developed in 1990 and updated in 1997 (NWFWMD 1997).
The Pensacola Bay system is inclusive of the interconnected estuarine waterbodies of Escambia Bay, Pensacola Bay, Blackwater Bay, East Bay and Santa Rosa Sound; the Escambia, Blackwater, East Bay Yellow, and Shoal rivers; and the greater contributing watershed. The watershed extends from southern Alabama south to the Gulf of Mexico. Within Florida, it includes portions of Escambia, Santa Rosa, Okaloosa, and Walton counties. Although about two-thirds of the contributing watershed is within Alabama, the scope of this plan for implementation purposes is limited to the Florida portion.
The Pensacola Bay system provides important environmental functions with numerous benefits and services for surrounding communities. Among watershed services are water storage and flood attenuation, groundwater recharge, regulation of discharge to receiving waters, water quality protection, cycling of energy and nutrients, erosion control, and stream bank stabilization. Additional human benefits are usable surface and ground waters, fish and wildlife resources, recreational opportunities, aesthetic characteristics, and associated economic benefits.
1.1 SWIM Program Background, Goals, and Objectives
Surface Water Improvement and Management plans are developed pursuant to the SWIM Act, enacted by In addition to the SWIM Act of 1987, the following Florida statutes and rules support the Florida Legislature in 1987 and amended in 1989 and complement the SWIM program: through sections 373.451-373.459, Florida Statutes (F.S.). Through this Act, the Legislature recognized Chapter 259, F.S.: Florida Forever Act threats to the quality and function of the state's surface Chapter 375, F.S.: Land Acquisition water resources. The Act authorized the state’s five Trust Fund water management districts to: Section 403.067(7)(a)4, F.S.: Total Develop plans and programs to improve Maximum Daily Loads (TMDLs) management of surface waters and associated Section 373.042, F.S.: Minimum Flows resources; and Minimum Water Levels Identify current conditions and processes Chapter 62-43, Florida Administrative affecting the quality of surface waters; Code (F.A.C.): Surface Water Develop strategies and management actions to Improvement and Management Act restore and protect waterbodies; and Chapter 62-302, F.A.C.: Surface Water Quality Standards Conduct research to improve scientific understanding of the causes and effects of the Chapter 62-303, F.A.C.: Identification degradation of surface waters and associated of Impaired Surface Waters; and natural systems.

2 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT 2.0 Watershed Description
2.1 Geographic and Geological Characteristics
The contributing watershed of the Pensacola Bay system covers Pensacola Bay system approximately 4,371,534 acres extending from southern Alabama watershed attributes: through the western Florida Panhandle. The watershed includes three major rivers: the Escambia, Blackwater, and Yellow rivers, as well as Two states: Alabama the smaller East Bay River. These, in turn, discharge into the and Florida estuarine component of the watershed, which includes Escambia 4,371,534 acres Bay, Pensacola Bay, Blackwater Bay, East Bay, and Santa Rosa Sound. The Escambia River, the largest in the watershed, begins as Five interconnected the Conecuh River in Alabama. The Blackwater and Yellow rivers estuarine waterbodies also have their origins in southern Alabama. Three major river systems Within Florida, the watershed encompasses the majority of Escambia, Santa Rosa, and Okaloosa counties and the northwest Four Florida counties quadrant of Walton County (Figure 2-1). In Alabama, the watershed 31 distinct natural is mostly located in Covington, Escambia, and Conecuh counties; communities with smaller areas in Butler, Crenshaw, Pike, Montgomery, and Bullock counties.
Florida municipalities in the watershed include the cities of Pensacola, Gulf Breeze, Milton, Crestview, Century, Jay, Paxton, Laurel Hill, and Mary Esther. Unincorporated communities include Pensacola Beach, Warrington, Pace, Navarre, Navarre Beach, and Holt. The watershed also includes Naval Air Station (NAS) Pensacola and NAS Whiting Field, and a portion of the Eglin Air Force Base (AFB) reservation.

Source: FHWA 2014; NOAA 2015a; USGS 2015, 2016a. Figure 2-2 Features of the Pensacola Bay Watershed (Florida Portion)
The overall watershed, including Alabama’s portion, lies within the Gulf Coastal Plain physiographic region, which is characterized by gently rolling hills, sharp ridges, prairies, and alluvial floodplains underlain by sediments of sand, gravel, porous limestone, chalk, marl, and clay. Within this greater physiographic region, the Florida portion of the watershed contains two localized physiographic regions: the Western Highlands and the Gulf Coastal Lowlands (USGS 2013).
The Escambia, Blackwater, and Yellow river basins are within the Western Highlands subsection of the Northern Highlands, which spans the northern Panhandle. The Northern Highlands region is characterized by greater topographic relief than the Gulf Coastal Lowlands and contains extensive clay deposits overlying limestone bedrock of the Citronelle formations, ancient delta deposits of clays, clayey sands, and gravel. The Western Highlands extend from 378 feet in elevation in Alabama down to a relict marine terrace of approximately 100 feet (Rupert 1993). The rolling hills of the Western Highlands have sandy soils and generally dry conditions, with groundwater emerging from lower slopes to create hillside seepage bogs (Wolfe et al. 1988).
The estuarine embayments are within the Gulf Coastal Lowlands; a region of successively higher, parallel terraces rising from the coast. Terraces of the Gulf Coastal Lowlands formed during the Pleistocene Epoch when fluctuating sea levels were associated with the growth and melting of ice caps. Dunes, barrier islands, beach ridges, and other topographical features were stranded inland as seas receded. Land
4 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT surfaces are generally level and less than 100 feet above sea level. Substantial areas are less than 30 feet above sea level and are characterized by extensive wetlands. Higher elevations are present in the general area of Pensacola, on the west side of Escambia Bay and the north side of Pensacola Bay.
The watershed of the Pensacola Bay system follows much of the general stratigraphy of the western Florida Panhandle. Many of the watershed’s geologic features are a product of prehistoric marine deposition during periods when sea level was higher than the present. Near-surface formations within Florida’s portion of the watershed include dolomitic limestones, sandy clayey limestones, shell beds, clayey sands, and sands (Scott 2001). Overlying most geologic formations are unconsolidated Holocene (11,700 years ago to the present) siliciclastic sediments (nearly pure quartz sands with minor heavy mineral sands) (Scott 2001). These were deposited during sea level fluctuations and are presently found on the barrier islands.
In the upper portion of the watershed, the Citronelle Formation forms the stream-incised hills of the Western Highlands and forms a distinct bluff at Bay Bluff, along the western shore of Escambia Bay (USDA 2004). Additionally, the Miocene (origins 23.3 to 5.3 million years before present) Alum Bluff Group is found along the upper reaches of the Yellow and Shoal rivers.
Most of the southern boundary of Escambia and East bays is formed by the Fairpoint Peninsula, a sandy coastal barrier feature. The southern boundary of the system is formed by Santa Rosa Island, which is approximately 50 miles long and varying between approximately 1,000-1,500 feet wide (Morang 1992). The island is made up of Holocene quartz sands, between 15 and 30 feet thick, overlying a Pleistocene (2.6 million years to 11,000 years before present) core.
Soils in the southern portion of the watershed, in the vicinity of the estuary are predominantly of sandy composition. Soils in the northern reaches typically contain more organic matter and are of moderate permeability. Hydric soils are predominantly found along the floodplains of the major rivers and tributaries and other wetland systems. Detailed information about the watershed’s physiography, geology, and soils is provided in Appendix C.
2.2 Hydrologic Characteristics
2.2.1 Major Streams and Tributaries
The three major river systems of the watershed begin as blackwater streams in southern Alabama. Of these, the Escambia River is the largest, extending 240 miles from Escambia Bay to Pike County, Alabama, draining over 4,200 square miles across both states (90 percent within Alabama). The Yellow River extends approximately 110 miles from the eastern shore of Blackwater Bay to a point northeast of Andalusia, Alabama. The Yellow River is joined by its major tributary, the 33-mile Shoal River, near the City of Crestview. The Yellow River drainage basin covers 1,365 square miles, with 64 percent within Florida. The Blackwater River flows approximately 60 miles and drains 860 square miles, of which 81 percent is in Santa Rosa and Okaloosa counties. East Bay River, a smaller 15-mile river located in coastal Santa Rosa and Okaloosa counties, enters East Bay near Navarre and Eglin AFB. Average annual flows of the major river systems discharging into the Pensacola Bay system are listed in Table 2-1. Surface water features are shown in Figure 2-3.

In addition to the major rivers, there are numerous smaller tributaries of the rivers and estuary. Among these are Carpenter Creek, Pond Creek, Big Coldwater Creek, Pine Barren Creek, and Titi Creek, as well as drainages through numerous smaller embayments (bayous) along Pensacola, Escambia, East, and Blackwater bays.

2.2.2 Floodplains and Wetlands
As illustrated by Figure 2-4, extensive floodplains encompass the lengths of the Escambia and Yellow Rivers. Major wetland systems are also within the Garcon Point and Fairpoint peninsulas, and within the headwaters of the East Bay River. Most of the floodplains within the watershed correspond with wetlands. Wetland communities are described further in Section 2.4.

2.2.3 Coastal Waterbodies
Estuarine waters of the Pensacola Bay system, including Pensacola Bay, Escambia Bay, Blackwater Bay, East Bay, and Santa Rosa Sound, encompass approximately 187 square miles. The estuary exhibits a low tidal range with limited flushing and circulation and vertical salinity stratification (Olinger et al. 1975). Conditions in Escambia, Pensacola, Blackwater, and East bays are heavily influenced by riverine inflow.
Pensacola Bay is located in Escambia and Santa Rosa counties and has an approximately one-half mile wide pass to the Gulf of Mexico. Escambia and East Bays adjoin Pensacola Bay, along with bayous Texar, Chico, and Grande. Escambia Bay is immediately north of Pensacola Bay and covers roughly 36 square miles between Garcon Point on the east and Magnolia Point to the west. The primary source of fresh water inflow to Escambia and Pensacola bays is the Escambia River. Additional freshwater sources are Pace Mill Creek, Carpenter Creek, and Jones Creek, as well as the contributing basins of several bayous.
Located at the mouth of the Blackwater River, Blackwater Bay covers approximately 10 square miles and is influenced by inflow from the Blackwater and Yellow rivers. East Bay adjoins Blackwater Bay at Escribano Point and Pensacola Bay between Garcon Point and Redfish Cove. The shoreline along Escribano Point and areas of Garcon Point are largely undeveloped.
Santa Rosa Sound is a 42-square-mile lagoon extending from Pensacola Bay and Gulf Breeze in the west to its confluence with Choctawhatchee Bay. The Sound is bordered to the north by the Fairpoint Peninsula and Santa Rosa Island to the south.
7 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
A prominent characteristic of the Pensacola Bay system estuary is a series of bayous that define much of the littoral zone. Bayous Grande, Chico, and Texar intersect with the City of Pensacola and NAS Pensacola. The drainage basins contributing to these bayous include Jones Swamp and Creek and Carpenter Creek. Major bayous on Escambia Bay in Santa Rosa County are Mulatto Bayou and Indian Bayou. The City of Gulf Breeze also has large bayous on the south shore of Pensacola Bay.
2.3 Land Use and Population
Land use and land cover across the greater Pensacola Bay system watershed, including Alabama, is predominantly upland forest, with substantial portions also consisting of wetlands, agricultural lands, and developed areas (Figure 2-5).
Source: FDEP 2015a, USGS 2011 Figure 2-5 Interstate Land Cover: Pensacola Bay System Watershed
Within Florida, upland forest encompasses nearly half of the watershed. Wetlands encompass nearly 20 percent of the watershed, with agricultural and developed lands each comprising approximately 14 percent of the watershed (Table 2-2).

Urban development is concentrated in the southern and southwestern portion of the watershed, mostly within the Pensacola metropolitan area. This development extends south and east from the City of Pensacola to include Navarre, Pace, Pensacola Beach, Milton, and Gulf Breeze. Urban development in the northern portion of the watershed is mostly localized around the City of Crestview in Okaloosa County.
8 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Agricultural lands are concentrated in northern Escambia County, central and northern Santa Rosa and Okaloosa counties, and northern Walton County. Floodplains and wetlands are concentrated along the Escambia and Yellow Rivers, Garcon Point, and the East Bay River and Jones Creek basins. Generalized land use and land cover within Florida are presented in Figure 2-6.
Source: FDEP 2015a Figure 2-6 2012-2013 Land Use and Land Cover
Public lands in the watershed include the Blackwater, Escambia, and Yellow River water management areas (WMAs), Gulf Islands National Seashore, Blackwater River State Forest, several state parks, and U.S. Department of Defense lands. These lands provide a buffer system that helps protect water quality, provide flood protection, and sustain integrated terrestrial and aquatic ecosystems. The District’s WMA lands cover approximately 55,592 acres along the Escambia, Blackwater, and Yellow rivers and the Garcon Point peninsula. Gulf Islands National Seashore encompasses approximately 3,000 acres on Santa Rosa Island. Among state lands in the watershed are the Escribano Point Wildlife Management Area, Blackwater River State Forest, and the Blackwater River and Yellow River Marsh Preserve state parks. Public and conservation lands are discussed in more detail in Appendix G.

2.4 Natural Communities
This section provides a summary of habitats and natural communities found in the watershed, particularly those most-influenced by surface water management activities, as well as information about some of the more important biological resources associated with them. More detailed information on the habitats and natural communities observed in the Pensacola Bay watershed, as well as the species those habitats support, are described in Appendices D and E.
Lewis et al. (2016) estimate that the Pensacola Bay system supports at least 1,400 estuarine plant and animal species, in addition to migratory species. Aquatic habitats within the watershed include salt marshes, seagrass beds, and oyster reefs. These habitats support wintering migratory waterfowl and many marine organisms, including juvenile sea turtles and commercially and recreationally important fish and shellfish. More than 200 species of fish and shellfish have been reported in the waters of the Pensacola Bay system, including five diadromous species: Alabama shad (Alosa alabamae), skipjack herring (Alosa chrysochloris), hogchocker (Trinectes maculatus), Gulf sturgeon (Acipenser oxyrhynchus desotoi), and American eel (Anguilla rostrate) (FDACS 2013b).
2.4.1 Terrestrial Communities
Terrestrial habitats within the Pensacola Bay watershed include bluffs, longleaf pine-wiregrass forests, mesic flatwoods, sandhill and scrub communities, scrubby flatwoods, slope forests, upland hardwood forests, wet flatwoods, and xeric hammock. The conditions of these habitats vary widely across the watershed, depending on land use, land management, and other factors.
Many of the native pine forests have been cut for timber, cleared for agriculture, or intensively managed for silviculture. As a result, the watershed’s uplands are now a mosaic of natural regeneration forests, pine plantations, agricultural lands, and developed areas (NWFWMD 1990). Terrestrial communities also support a number of threatened and endangered species. Federally listed species within the watershed include the gopher tortoise (Gopherus polyphemus), gopher frogs (Rana capito), the reticulated flatwoods salamander (Ambystoma bishopi), the eastern indigo snake (Drymarchon corais couperi), and the red- cockaded woodpecker (Picoides borealis). All have been documented on the watershed’s conservation lands including the Blackwater River State Park (FDEP 2016a). The Blackwater River State Forest is part of a series of contiguous conservation lands, including the Conecuh National Forest and Eglin AFB. Together, these lands constitute the largest remaining contiguous area of the mature longleaf pine forest ecosystem in the world and support one of the largest populations of red-cockaded woodpecker habitat on public lands (FDACS 2013b).
10 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
2.4.2 Major Rivers
The Escambia River is a large alluvial river that carries a heavy sediment load and has substantial variation in flows and a diversity of aquatic and wetland habitat types. The upper river (within Florida) is sand-bottomed, with sand bars and beaches forming along the inside arcs of river bends. According to Bass (1990), in-stream vegetation tends to be lacking, with habitat primarily provided by snags, exposed tree roots, and undercut banks. Bottomland hardwood forest and oxbow lakes border the main river, and pine forest occupies much of the riparian zone.
The Blackwater River and its tributaries are relatively shallow sand-bottomed streams. The lower river is tidally influenced, with large basins that provide additional habitat diversity. The Yellow River intersects the Western Highlands Region, creating substantial bluffs, prior to discharging into Blackwater Bay from the east. The Yellow River is described as a sand bottom river and is characterized by shallow clear-tan waters. Its primary tributary, the Shoal River, originates in Walton County. Titi Creek is the major tributary of the Shoal River.
The Escambia and Conecuh rivers, as well as several tributaries, are designated as critical habitat for the threatened Gulf sturgeon (Acipenser oxyrinchus desotoi). Additional critical habitat area is within the lower Blackwater River, the Yellow River, and the Shoal River from its confluence with the Yellow River to the U.S. Highway 85 overpass. Within the critical habitat are discrete areas that serve as potential spawning locations during the spring high flow events, and as summertime holding areas. These summertime holding areas are extremely important to the survival of the sturgeon, since the fish do not migrate to the estuary and gulf until the fall. The quality of the holding areas is also thought to be a significant factor in the reproductive health of the female sturgeon.
The main channel holding areas are often moderately deep to deep (~3-7 meters) runs, glides, gradual bends, or pool tail-outs. Main channel areas occurring immediately downstream of springs, tributaries, or distributary confluences are sometimes selected as holding areas, perhaps due to the water depth, water velocity, cool water influences of the tributary, or water chemistry. The second primary river habitat where sturgeon can be found are off-channel areas that are sheltered from the primary current of the main channel. These mesohabitats are often described as sloughs, bowls, or basins and typically have a deep and open connection to the main channel (Kaeser, 2016). Estuarine waters within the Pensacola Bay system are also designated critical habitat for the Gulf sturgeon, providing important winter habitat.
The Escambia, Yellow, and Shoal rivers provide critical habitat for several species of threatened and endangered freshwater mussels. The Escambia River includes critical habitat for the Round ebonyshell (Fusconaia rotulata), Choctaw bean (Villosa choctawensis), fuzzy pigtoe (Pleurobema strodeanum), southern kidneyshell (Ptychobranchus jonesi), southern sandshell (Hamiota australis), and narrow pigtoe (Fusconaia burkei). The Escambia River in Alabama also includes critical habitat for the Alabama Pearlshell (Margaritifera marrianae). The Yellow River system includes critical habitat for the Choctaw bean, narrow pigtoe, southern sandshell, and fuzzy pigtoe.
2.4.3 Riparian, Palustrine, and Floodplain Habitats
Riparian habitats include those areas along waterbodies that serve as an interface between terrestrial and aquatic ecosystems. Riparian areas are important fish and wildlife habitats that promote ecological diversity and assist in mitigating or controlling NPS pollution. Riparian vegetation can be effective in removing excess nutrients and sediment from surface runoff and shallow groundwater and in shading streams to optimize light and temperature conditions for aquatic plants and animals. Riparian vegetation, especially trees, is also effective in stabilizing streambanks and slowing flood flows, resulting in reduced
11 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT downstream flood peaks. Major floodplains within the watershed are found along the Escambia, Yellow, Shoal, and Blackwater rivers.
Pitcher plant bogs can be found scattered throughout the Blackwater River State Forest, Yellow River Marsh Preserve State Park, and Garcon Point Water Management Area (FDACS 2013b; Florida Division of Recreation and Parks 2016c; FNAI 2010). They occur in isolated depressions of somewhat poorly drained soils and contain a high diversity of rare plants. American chaffseed (Schwalbaea americana), a federally endangered species, has been documented at one of the seepage slopes in the Blackwater State River Forest (FDACS 2013b).
The Yellow River Marsh Preserve State Park includes tracts of wet prairie classified by the FNAI as imperiled habitats in the State of Florida because of their rarity (Florida Division of Recreation and Parks 2016c; FNAI 2010). Nearly 20 rare and endangered species of plants and animals make their homes in the wet prairies, dome swamps, and flatwoods of the park. Wet prairies support some of the most diverse plant communities in the southeast including a population of unique carnivorous plants (Florida Division of Recreation and Parks 2016c).
2.4.4 Emergent Marsh
In the salt marshes and nearshore tidal areas, species are adapted to the highly variable temperatures and salinities. Some species migrate in and out as necessary to take advantage of the food and shelter derived from the primary coastal habitats such as oyster reefs, marshes, and seagrasses (Lewis et al. 2016). Salt marsh communities within the Pensacola Bay watershed include both tidal marsh and floodplain marsh. Marsh species composition is influenced by a combination of salinity tolerance and differences in soil type, elevations, and competitive interactions. Salt marshes are similar to brackish marshes in that they serve as a transition between terrestrial and marine systems. Generally, salt marshes are intertidal and develop along relatively low energy shorelines. Unlike brackish marshes, they may be found under significantly more saline conditions. Salt marshes in the Florida Panhandle are usually characterized by large, fairly homogeneous expanses of dense black needlerush (Juncus roemerianus). Often, they are accompanied on the water-ward side by smooth cordgrass (Spartina alterniflora). The Juncus and Spartina zones are distinctive and can be separated easily by elevation.
Salt marshes are among the most productive plant communities on Earth (Fernald and Purdum 1998). Among the species found in salt marshes are mussels, oysters, fiddler crabs (Uca sp.), marsh periwinkles (Littoraria irrorata), crown conchs (Melogena corona), mullet, and blue crabs. Emergent freshwater and brackish marshes are dominated by sawgrass (Cladium jamaicense), maidencane (Panicum hemitomon), giant cutgrass (Zizaniopsis miliacea), and cattails (Typha spp.), but may contain large interspersed patches of black needlerush. In contrast with more coastal salt marshes, these sites lack the extensive salt flats of saltgrass (Distichlis spicata), glasswort (Salicornia spp.), and salt barrens. Thirteen species of common waterfowl also winter in Pensacola Bay salt marshes (Lewis 1986).
Floodplain marsh occurs in the floodplains of the watershed’s major river systems. These marshes are seasonally inundated and are dominated by maidencane, pickerelweed (Pontederia cordata), sagittaria, buttonbush (Cephalanthus occidentalis), wax myrtle (Myrica spp.), and other mixed emergent vegetation. Floodplain marsh covers approximately 2,400 acres at the mouth of the Yellow River. In addition to the marsh species, patchy stands of hardwoods and water tolerant pine trees have become established on small "islands" of higher elevation in the marsh (Gardner 1991).

2.4.5 Seagrass Beds
Seagrass beds in the Pensacola Bay watershed (Figure 2-7) provide protective and foraging habitat for many marine species and are critical to the spawning cycle of many fish and invertebrate species, some of which are of great commercial and recreational significance. Among these are shrimp, spotted seatrout, Gulf menhaden, red drum or redfish, blue crab, Gulf flounder (Paralichthys albigutta), striped mullet (Mugil cephalus), and white mullet (Lewis et al. 2016). Seagrass meadows are largely limited to Santa Rosa Sound (Lewis et al. 2016). Seagrass beds are a protected habitat recognized by both the state and federal agencies. Five species of submerged aquatic vegetation have been found in Pensacola Bay and include: widgeon grass (Ruppia maritime), shoal grass (Halodule wrightii), manatee grass (Syringodium filiforme), star grass (Halophila engelmannii), and turtle grass (Thalassia testudinum) (Schwenning et al. 2002).
2.4.6 Oyster Reefs
The availability of hard substrate for colonization is a determining factor for the establishment of oyster reefs. Although hard substrate is not particularly common in the Pensacola Bay system, East Bay has historically supported healthy oyster populations. Oyster reefs have been widely demonstrated to improve water quality, protect shorelines by abating wave energy, stabilize bottom sediments, and provide habitat
13 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT for fish, crab, and other invertebrates (Lewis et al. 2016). The most current assessments report approximately 235 to 245 acres of oyster reef habitat within the Pensacola Bay system, including reefs that are closed for harvesting. Of this total area, it is estimated that approximately 75 percent of oyster reefs occur in East Bay (Lewis et al. 2016).
2.4.7 Coastal Barrier Systems
The Pensacola Bay watershed has a coastal barrier system consisting of Santa Rosa Island. The barrier system consists of many unique habitats and natural systems including beaches, foredune and relic dunes habitat, tidal marsh, brackish ponds and lagoons, coastal grasslands, and upland forest and scrub communities (National Park Service 2014). Barrier islands and peninsulas buffer adjacent bays and coastal areas from storm impacts and create calm saline conditions in landward waters, which promotes seagrass establishment. The majority of Santa Rosa Island is managed by the National Park Service as part of the Gulf Islands National Seashore. Pensacola Beach and Navarre Beach divide tracts of National Park Service land on the island.
14 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT 3.0 Watershed Assessment and Water Resource Issues
3.1 Water Quality
3.1.1 Impaired Waters
Of 350 waterbody segments in Florida’s portion of the Pensacola Bay system, the FDEP has identified 23 impaired segments with 26 total impairments, including 22 segments for bacteria (five for fecal coliforms, six for beach advisories, seven for shellfish harvesting classification, two for enterococci, one for Escherichia coli, and one for bacteria in shelfish), two segments for nutrients, and two segments for metals (FDEP 2017). Most estuarine waters have been listed as impaired for bacteria, and Escambia Bay has been listed for nutrients. Additional bacteria impairments are concentrated in the Yellow River and Blackwater River basins (Figure 3-1). The overall list of impaired waters may be found in Appendix F.
The FDEP identified seven waterbody segments as impaired for bacteria in the Pensacola Bay watershed, based on shellfish classifications issued by the FDACS (FDEP 2017): Escambia Bay North (waterbody identification number [WBID] 548AC; Escambia Bay (South Segment) (WBID 548B; Pensacola Bay (North Segment) (WBID 548C); Blackwater Bay (South Segment (WBID 548GB); East Bay (WBID 548H); East Bay River (Marine Portion) (WBID 701A); Tom King Bayou (WBID 833A); and
County health departments monitor recreational beaches for bacterial contamination and issue health advisories closing beaches when bacterial counts are too high. Beaches with more than 21 closures in a year are identified as impaired by FDEP. Six beach segments were identified as impaired for bacteria in the Pensacola Bay system, based on beach closures by local health departments (FDEP 2014a): Navy Point (WBID 548FB); Bayview Park Pier (WBID 738AB); Emerald Promenade Beachwalk (WBID 8007A); Navarre Park Highway 98 (WBID 915B); Liza Jackson Park (WBIB 915C); and Marler Park (WBID 915D).
15 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Source: FDEP 2017 Figure 3-1 Impaired Waters and TMDLs
Total Maximum Daily Loads (TMDLs) adopted for the Pensacola Bay system include 12 for fecal coliform, four for nutrients, one for DO, and 81 for mercury (Figure 3-1; Table 3-1) (FDEP 2016b). A TMDL represents the maximum amount of a given pollutant a waterbody can assimilate and still meet water quality standards, including applicable water quality criteria and designated uses. Established TMDLs identify specific reductions in pollutant loading required to restore water quality and meet restoration goals.
Total Maximum Daily Loads are implemented through Basin Management Action Plans (BMAPs), which identify specific management actions necessary to accomplish required pollutant reductions. Basin Management Action Plans are developed by local stakeholders (public and private) in close coordination with FDEP. A BMAP was adopted by FDEP in 2011 to implement five fecal coliform TMDLs and restore water quality in Bayou Chico located in the southern end of Escambia County (FDEP 2011, 2016d). The waterbodies addressed by the BMAP include Bayou Chico, which adjoins Pensacola Bay, and five additional waterbody segments that drain to Bayou Chico and the bay: Jones Creek, Jackson Creek, Bayou Chico Drain, Bayou Chico Beach (at Lakewood Park), and Sanders Beach (FDEP 2008a, 2008b, 2011b).
The BMAP was developed by FDEP in partnership with the City of Pensacola, Escambia County; the Escambia County Health Department, the Emerald Coast Utilities Authority (ECUA); the Florida
16 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Department of Transportation (FDOT); the Bayou Chico Association; the U.S. Navy, and the Bay Area Resource Council.

The FDEP adopted a statewide TMDL for reducing human health risks associated with consuming fish taken from waters impaired for mercury. Mercury impairments are based on potential human health risks, not exceedances of water quality criteria. The primary source of mercury is atmospheric deposition, with 30 percent from natural sources and 70 percent from anthropogenic international sources outside of North America. It is estimated that approximately 0.5 percent of mercury from anthropogenic sources is from Florida (FDEP 2013b). Only a small part of mercury in the environment is in the form of methylated mercury, which is biologically available to the food chain. The statewide TMDL for mercury includes a reduction target for fish consumption by humans and by wildlife and an 86 percent reduction in mercury from mercury sources in Florida (FDEP 2013b).
3.1.2 Pollution Sources
Nonpoint source (NPS) pollution is generated when stormwater runoff collects pollutants from across the landscape (lawns, pavement, highways, dirt roads, buildings, farms, forestry operations, and construction sites, etc.) and carries them into receiving waters. Pollutants entering the water in this way include nutrients, microbial pathogens, sediment, petroleum products, metals, pesticides, and other contaminants. Typical sources of NPS pollution include stormwater runoff from urban and agricultural lands and erosion and sedimentation from construction sites, unpaved roads, and destabilized stream banks. Atmospheric deposition of nitrogen, sulfur, mercury, and other substances via fossil fuel combustion also contribute to NPS pollution.
Stormwater runoff is the primary source of NPS pollution, and it is closely associated with land use. Urban land use, especially medium- to high-density residential, commercial, and industrial, generates the greatest NPS pollution per acre due to impervious surfaces that increase runoff. In urban areas, lawns, roadways, buildings, parking lots, and commercial and institutional properties all contribute to NPS pollution. Urban areas are largely concentrated within the coastal area, including the Pensacola metropolitan area, as well as the vicinity of Milton, the Fairpoint peninsula, portions of Santa Rosa Island, and nearby unincorporated communities. In addition to these established areas, the urban-rural fringe
17 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT hosts new development and construction sites, introducing new NPS pollution sources impervious surface area within the watershed.
In the Pensacola Bay watershed, a number of entities currently hold Municipal Separate Storm Sewer System ([MS4] NPDES Stormwater) permits for stormwater conveyances that discharge to waters of the state. These include the following: Hurlburt Field City of Mary Esther Eglin AFB Walton County University of West Florida City of Gulf Breeze NAS Pensacola City of Milton City of Ft. Walton Beach City of Pensacola Santa Rosa County Town of Century Okaloosa County Escambia County
In 1991, Escambia County established a Stormwater Master Plan Program to reduce the frequency and severity of flooding and to improve water quality in receiving surface waters (Curb 2011). Among the project needs identified were road paving, restoring streams, and installing stormwater retrofits in established neighborhoods. Projects have been funded primarily through the county’s local option sales tax (LOST). The City of Pensacola has also prioritized needed stormwater improvements, including within such areas as Piedmont Road area, Aragon Court, downtown Pensacola, Long Hollow Basin, and others.
Fertilizer application, ditching, road construction, and harvesting associated with agriculture and silviculture can also cause NPS pollution, erosion, sedimentation, and physical impacts to streams and lakes (Stanhope et al. 2008). Within the watershed, agricultural lands are concentrated most prominently in northern Escambia County, central and northern Santa Rosa and Okaloosa counties, and northern Walton County (Figure 2-6). Silviculture is widespread across all non-urban areas of the watershed.
Erosion and sedimentation are natural phenomena that can be accelerated by human activities, with undesirable water quality consequences. Factors such as highly-erodible soils, unstable slopes, and high rainfall intensities are important factors in erosion and sedimentation. Construction activities, unpaved roads, abandoned clay pits, and agricultural and silvicultural practices lacking proper BMPs are common sources of sedimentation. Accelerated stream bank erosion caused by runoff associated with impervious surfaces can also be a significant source of sedimentation into receiving waters.
Freshwater streams across the watershed have been impacted by the erosion of dirt roads and deposition of sediment into waterways. In addition to benthic habitat impacts, this sedimentation causes turbidity within the directly affected streams and downstream receiving waters, extending into the major rivers and estuarine waterbodies.
Onsite sewage treatment and disposal systems are widespread sources of nutrients and other pollutants. Concentrations of OSTDS can degrade the quality of groundwater and proximate surface waters. While conventional OSTDS can control pathogens, surfactants, metals, and phosphorus, mobility in the soil prevents complete treatment and removal of nitrogen. Dissolved nitrogen is frequently exported from drainfields through the groundwater (NRC 2000). Additionally, OSTDS in areas with high water tables or soil limitations may not effectively treat other pollutants. Pollutants can enter surface waters as seepage into drainage ditches, streams, lakes, and estuaries (EPA 2015d; NRC 2000).
18 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
In the Pensacola Bay watershed, most rural and unincorporated communities and a number of suburban communities rely on OSTDS for wastewater treatment. New septic installations have declined since the late 1970s. By the early 1990s, new septic installations in Escambia County had declined by 50 percent (Figure 3-2); however, other counties in the watershed have replaced septic systems more slowly (FDOH 2015b).
Florida Water Management Inventory data indicate approximately 54,000 known or Source: FDOH 2015b. likely septic systems in the Figure 3-2 Number of New Septic Tank Permits by Year watershed (FDOH 2016). Known septic is based on permit data combined with inspection records. Likely septic is based on results of the review of nine criteria, but without inspection verification. Figure 3-3 shows the approximate locations of septic tanks as of 2015 (FDOH 2015b).

19 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Marinas may be a source of NPS pollution from typical activities, such as boat maintenance, fueling, and marine sewage discharge, and due to runoff from parking lots. Pollution from marinas can depend on the availability of pump-out facilities and the level and consistency of marina BMP implementation. At the time of this writing, there are nine FDEP-certified Clean Marinas in the watershed.
Some pollutants, such as nitrogen and mercury, are also contributed to the landscape and waterbodies by atmospheric deposition. Most oxidized-nitrogen emissions are deposited close to the emission source and can especially impact surface water proximate to urban areas (Howarth et al. 2002a, 2002b, 2002c; NRC 2000).
There are 26 permitted domestic wastewater facilities and 33 industrial wastewater facilities within the watershed, as well as one power plant (Figure 3-5). Since completion of the previous SWIM plan update, a major accomplishment has been the relocation of the ECUA’s Main Street WWTF in downtown Pensacola to its current location as the Central Water Reclamation Facility, located near Cantonment. The previous facility had a permitted surface water discharge of 20 million gallons per day. With the new facility, all surface water discharge into the bay has been eliminated, and 100% water reclamation is being achieved. The majority of the reclaimed water is being reused for beneficial purposes. Domestic wastewater facilities in the Pensacola Bay system watershed are listed in Table 3-2.

Mining and extraction activities near waterbodies have the potential to cause turbidity, sedimentation, and smothering. Mining activities within the watershed are concentrated in the vicinity of the Town of Century, in the Pensacola metropolitan area, and south of Milton. The USGS recognizes nine major mining operations within the watershed, including one perlite mine, two sulfur mines, and six sand and gravel mines. FDEP identifies 59 mines and borrow pits within the watershed; many are located near streams, creeks, tributaries, and other waterbodies (FDEP 2014d, 2015c). Of these, there are 42 sand mines, four clay mines, and 13 sand and clay mines.
The extensive and historical industrial and manufacturing facilities in the Pensacola urban area have had a profound effect on the bay system. Degradation of water and/or sediment by toxic chemicals, such as those used in industrial and manufactural processes, can impact surface water quality and the health of associated upland and aquatic habitats and generate contaminated food chains in which top predators are most significantly harmed. Chemical contaminants can also be harmful to humans, particularly through consumption of seafood containing elevated quantities of mercury, polychlorinated biphenyls, dioxin, and other harmful chemicals.
There are currently five U.S. EPA National Priority List (NPL) Superfund sites within the Pensacola Bay watershed: Agrico Chemical Co.; American Creosote Works, Inc.; Escambia Treating Co.; NAS Pensacola; and NAS Whiting Field.
The Agrico Chemical Company and Escambia Wood-Pensacola sites are about one mile west of Bayou Texar. Contaminated groundwater from these sites appears to be migrating into Bayou Texar (Mohrherr et al. 2005). The American Creosote Works site covers 1.5 acres in Pensacola, Florida, about 0.3 miles north of where Bayou Chico joins with Pensacola Bay. The USGS identified phenols in groundwater associated with American Creosote Works (USGS 1986). Efforts to identify, evaluate, and clean up contaminant sites at NAS Pensacola and NAS Whiting field are outlined by EPA (2016d).
In Florida’s portion of the watershed, there are 28 hazardous waste facilities registered as EPA Biennial Reporter facilities. Of these, 14 are in Pensacola. Biennial Reporter facilities handle hazardous waste and are required to report to the EPA at least once every two years (EPA 2016c). Additionally, 389 active petroleum contamination tracking sites within the watershed are registered with the state’s Storage Tank and Petroleum Contamination Monitoring (STCM) database. There are 34 contaminated dry cleaning sites within the basin eligible for the state-funded Dry Cleaning Solvent Cleanup Program. The majority of STCM and dry cleaning sites are located in historically developed areas in Pensacola and Milton, with additional sites in other developed areas, including Crestview, Jay, Gulf Breeze, Baker, and other unincorporated communities.
There are also 19 non-NPL Superfund sites located within the basin, 14 are located in Pensacola. A non- NPL site is a Superfund site that has not been placed on the NPL list through the EPA’s formal process for assessing hazardous waste sites; however, the EPA can take short-term cleanup actions on non-NPL sites under the emergency removal program.
22 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT 3.2 Natural Systems
Eutrophication has been documented in several waterbodies across the Pensacola Bay watershed, primarily in the bays and estuaries of the watershed. Compared to other eutrophic estuaries, concentrations of nutrients within Pensacola Bay are relatively low (Bricker et al. 2007). Some nutrient concentrations have been declining within the Pensacola Bay system, reaching levels below the concentrations of concern for aquatic vegetation (FDEP 2012). The State of Florida water quality criterion for chlorophyll-a and aquatic life designated use is ≤ 20 micrograms per liter, which is well above most measured concentrations for the Pensacola Bay system (FDEP 2010). However, despite relatively low nutrient concentrations, Pensacola Bay exhibits some classic eutrophication symptoms, including summer hypoxia, significant loss of sea grass habitat, and phytoplankton dynamics indicative of variations in freshwater flows (Caffrey and Murrell 2016).
Hypoxia commonly occurs within the Pensacola Bay estuarine system, particularly in stratified waters in Escambia and East bays (Hagy and Murrell 2007). The extent of this condition, at times affecting up to 30% of the estuary, suggests it could be a significant factor structuring biological communities and habitat. Contributing factors may include salinity stratification associated with tidal and freshwater inflow and nutrient enrichment of plankton and sediments (Murrell et al. 2009).
Chemical contaminants within the sediments have been observed in many areas of the estuary, particularly within bayous Chico and Texar and in Escambia Bay. DeBusk, et al. (2002) details compiled monitoring results, describing fairly consistent patterns of contaminant distribution. Shuba (2012) describes monitoring and recommendations related to polychlorinated biphenyl (PCB) enrichment. Metals, polycyclic aromatic hydrocarbons (PAHs), and dichlorodiphenyltrichloroethane (DDT)-related compounds were consistently found to be elevated in bayous Chico and Texar and in Escambia Bay, and to a lesser extent in Bayou Grande and East Bay. Polychlorinated biphenyls, which entered the system apparently through a spill in 1969 (NWFWMD 1997), have continued to be found in the sediments of the lower Escambia River and Escambia Bay. Lewis et al. (2016) and U.S. EPA (1998), further describe sediment contaminants and toxicity in bayous Texar and Chico, Escambia Bay, and elsewhere within the Pensacola Bay estuary. Pensacola’s urbanized bayous have long been subject to extensive stormwater runoff and NPS pollution, as well as historical point source discharges and industrial development. As a result, water and sediment quality in these areas have been significantly impacted. These contaminants, substantially representing historical pollutant discharges, represent a source of legacy pollutants that may continue to degrade benthic habitats and be subject to resuspension with availability to the water column.
In 2010, portions of Pensacola Bay, particularly near Pensacola Pass and proximate locations in Santa Rosa Sound and Big Lagoon, were repeatedly exposed to crude oil and weathered residue from the Deepwater Horizon oil spill.
Sedimentation more broadly affects benthic habitats in portions of the watershed due to poor flushing and the input of large sediment loads from the river basins and from stormwater runoff. George (1988) concluded that the percentage of fine-grained sediments (clays and silts) increased since the 1960s, with the percentage of fine-grained sediments in East Bay doubling between 1968 and 1988. Another example is Carpenter Creek, which suffers from streambank erosion and channelization, thus impact in receiving waters in Bayou Texar.
Between 1950 and 1980, about 95 percent of seagrass habitat disappeared from the Pensacola Bay system (Yabro and Carlson 2016). Recognizing the importance of seagrasses for fisheries and for human benefits, Lewis et al. (2016) estimated that losses in seagrass habitat from 1960-2010 equate to an economic loss of approximately $104 million per year (1991 dollars) in ecosystem services.
23 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Yabro and Carlson (2016) report that from 2003 to 2010 and found that coverage in Pensacola Bay in 2010 was approximately 1,053 acres, an increase of approximately 51 percent from 2003. An increase was noted in Pensacola Bay, in particular. Losses of about five percent, however, were reported from Santa Rosa Sound. Ongoing stressors of seagrasses in the Pensacola Bay system may include effects of hypoxia, salinity changes, and burial from sediments (Yabro and Carlson 2016).
Central and southern East Bay and shoreline areas of Escambia Bay suffered nearly complete losses of seagrasses since the 1940s (Olinger et al. 1975; Yabro and Carlson 2016). In some areas, water quality may have recovered sufficiently to support seagrasses; thus, additional efforts to identify barriers and strategies for recovery are warranted.
Estimates of recent oyster reef coverage (approximately 245 acres) in the Pensacola Bay system are lower than published estimates from the 1970s-1990s, which report coverage of several thousands of acres (Lewis et al. 2016). From the 1960s-1980s, shellfish (primarily oysters) reportedly experienced significant declines, attributed to fungal parasites, poor water quality, heavy rainfall, and dredging. The Florida Department of Natural Resources, now FDEP, reported periodic crashes in oyster populations within the Yellow River Marsh Aquatic Preserve, with near 100 percent mortality rate (Gardner 1991).
Lewis et al. (2016) estimated 2014 salt marsh area at 6,697 acres. Portions of the bay system have experienced increases in salt marsh coverage. Salt marsh coverage increased from 1,400 to 1,794 acres in Blackwater Bay, 3,750 to 4,519 acres in Escambia Bay and from 59 to 103 acres in Pensacola Bay. Coverage has remained relatively stable for East Bay. Total salt marsh coverage across the basin has increased 19 percent (1995-2010) and is expected to further increase due to sea level rise if not restricted by anthropogenic barriers such as roadways, and armored shorelines (Lewis et al. 2016).
In rural areas, land clearing associated with agriculture, silviculture, and recreation, as well as dirt road erosion, have increased sedimentation in the Blackwater River basin. The heavy use of vehicles on unpaved roads in Blackwater River State Forest has increased soil erosion, leading to higher turbidity in streams and smothered aquatic habitat (FDACS 2013b). Agricultural land use, unpaved roads, and heavy rain events have also caused turbidity in Yellow river (FDEP 2016d).
3.3 Floodplains and Floodplain Management
Floodplains protect water quality by allowing storage of floodwaters, reducing runoff velocity and preventing erosion and sedimentation. Floodplains also attenuate potential flood effects while providing an ecological link between aquatic and upland ecosystems and habitat for many terrestrial and aquatic species. Development of and encroachment into floodplains reduces water storage capacity, increases flood heights and velocities, and degrades natural systems in areas beyond the encroachment itself.
Maintaining the hydrological integrity of the floodplain benefits surface water systems in drought conditions, as well as flood conditions. Floodplain vegetation reduces evaporation and increases soil water storage capacity. Riparian wetlands, marshes, and floodplain forests help to slow stormwater runoff, protecting water quality and regulating the release of water into streams and aquifers.
Riverine floods are common along the watershed’s major rivers and tributaries. Wetlands, low-lying areas, and coastal areas are also subject to significant flooding. Federal Emergency Management Agency flood maps delineate 269,577 acres (approximately 18 percent) of the Pensacola Bay watershed as Special Flood Hazard Area (Figure 2-4). Lands most prone to flooding are predominantly on Santa Rosa Island, Garcon Point, Escribano Point, and along the major rivers.
24 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
The coastline within the Pensacola Bay watershed is protected by offshore barrier islands and peninsulas; however, the coastal areas of Santa Rosa, Escambia, and Okaloosa counties are subject to flooding from coastal surges associated with hurricanes (FEMA 2006). Another flooding source is the East Bay River. Flooding in the Blackwater River Basin is caused by stream overbank flow and hurricane storm surges, and sometimes a combination of both. Riverine flooding occurs frequently and is prevalent throughout the reach of the river where the riverbanks are low and the floodplain is wide. The coastline in Santa Rosa County is subject to widespread flooding resulting from storm surges that accompany hurricanes and other severe storms from one or more of the following flooding sources: the Gulf of Mexico, East Bay, Escambia Bay, Pensacola Bay, Blackwater Bay, and Santa Rosa Sound (FEMA 2014).
25 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT 4.0 Watershed Protection and Restoration
4.1 Management Practices
Watershed protection and restoration is inherently a collaborative effort on the part of state, regional, and federal agencies; local governments; nongovernment organizations; the business community; and the public. Implementation is conducted at the watershed, sub-watershed, and local scale. Recommended management strategies are described below.
4.1.1 Nonpoint Source Pollution Abatement
Addressing NPS pollution is a vital part of watershed management in the Pensacola Bay system. As described above, stormwater runoff carries pollutants from the landscape that diminish water quality, and it can physically impact streams and aquatic habitats. Multiple strategies can be employed to collectively reduce NPS pollution and protect and improve water quality and watershed resources.
Stormwater Retrofit
Among the most effective means of reducing NPS pollution is to retrofit existing stormwater management systems to add treatment and restore or approximate natural hydrology. In addition to improving water quality, appropriately designed retrofit projects improve flood protection, reduce physical disturbance from erosion and sedimentation, and provide aesthetic and recreational use benefits.
Implementation may include a mixture of traditional and nonstructural approaches. There are numerous methods of stormwater management and treatment, among which are wet and dry detention ponds, infiltration systems, stormwater harvesting, wetland treatment systems, stormwater separator units, vegetated swales and buffers, pervious pavement, bioretention, ditch blocks, green roofs, and chemical (alum) treatment. Specific measures employed depend on site conditions, including soils, water table conditions, flow, intended uses, and available land area. Optimally, a treatment train approach is employed, addressing hydrology and water quality treatment across a basin. Implementation is best accomplished within a wider, watershed context that incorporates initiatives such as Florida Friendly Landscaping (section 373.185, F.S.) and public outreach and awareness.
Within the Pensacola Bay watershed, the greatest need and potential for stormwater retrofit efforts is within municipal and fringe areas with relatively dense development and significant areas of impervious surface. Examples include the Pensacola metropolitan area, Gulf Breeze, Navarre, Mary Esther, Milton, and Crestview. Local governments normally take the lead in implementing stormwater retrofit projects, as they most commonly own, operate, and maintain stormwater management systems.
Agricultural Best Management Practices
Best management practices are practical measures that act together or individually to protect water resources and fish and wildlife habitat. Such practices were pioneered for agriculture but have also been developed and effectively applied to silvicultural and urban land uses. Best management practices reduce soil loss, nutrient enrichment, sedimentation, discharge of chemical pollutants, and other adverse impacts (see, for example, Wallace et al. 2017, among many others). Implementation also often benefits stream bank stability and fish and wildlife habitat. In addition to protecting water and habitat quality and conserving water, BMPs can reduce costs to producers by increasing operational efficiency and effectiveness.
26 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Agricultural BMPs include both structural and nonstructural controls. Examples are cover crops, contour farming, terracing, tree planting, integrated pest management, mobile irrigation laboratory applications, sod-based crop rotation, fertigation, and many other tools and services. The Florida Department of Agriculture and Consumer Services has developed, evaluated, and approved BMPs specific to individual agricultural operations within Florida watersheds. Guidance for and assistance in enrolling in approved BMPs are provided by FDACS. Cost share programs are also conducted both by FDACS and the District. Additionally, FWC provides technical assistance to private landowners through its Landowner Assistance Program.
Implementation of approved BMPs or water quality monitoring is required in basins with adopted BMAPs. Whether required or not, however, BMPs are effective means of protecting and restoring watershed resources and functions and are recommended land use practices for implementation of this plan.
Within the Pensacola Bay watershed, the most extensive and concentrated areas of agricultural land use are within northern Escambia and Santa Rosa counties, notably including the Pine Barren Creek, Moore Creek, and Coldwater Creek sub-basins (Figure 2-6). Within these areas in particular, application of agricultural BMPs have significant potential to further protect and improve water quality and aquatic habitat conditions.
Silviculture Best Management Practices
The Florida Forest Service (FDACS 2008) defines silviculture BMPs as “the minimum standards necessary for protecting and maintaining the State’s water quality as well as certain wildlife habitat values, during forestry activities.” These practices are protective of water resources, including streams, downstream receiving waters, sinkholes, lakes, and wetlands. The FFS provides specific guidance on BMPs and has established compliance monitoring requirements and procedures. FDEP (1997) evaluated the effectiveness of silviculture BMPs and concluded that forestry operations conducted in accordance with the BMP manual resulted in no major adverse habitat alterations.
The primary BMPs established for forestry are special management zones (SMZs). These zones provide buffering, shade, bank stability and erosion-control, as well as detritus and woody debris. They are intended to protect water quality by reducing or eliminating sediment, nutrients, logging debris, chemicals, and water temperature fluctuations. They also maintain forest attributes that provide wildlife habitat. Widths of SMZs vary depending on the type and size of the waterbody, soils, and slope. Specific SMZs are described as follows. 1) The Primary Zone varies between 35 and 200 feet and applies to perennial streams, lakes, and sinkholes, OFWs, Outstanding Natural Resource Waters (ONRW), Class I Waters, and, in some cases, wetlands. A primary zone generally prohibits clear-cut harvesting within 35 feet of perennial waters and within 50 feet of waters designated OFW, ONRW, or Class I. Other operational prescriptions also apply to forestry practices to protect water and natural resources. 2) The Secondary Zone applies to intermittent streams, lakes, and sinkholes. Unrestricted selective and clear-cut harvesting is allowable, but mechanical site preparation, operational fertilization, and aerial application or mist blowing of pesticide, are not. Loading decks or landings, log bunching points, road construction other than to cross a waterbody, and site preparation burning on slopes exceeding 18 percent are also prohibited. These zones vary in width between 0 and 300 feet. 3) The Stringer provides for trees to be left on or near both banks of intermittent streams, lakes, and sinkholes to provide food, cover, nesting, and travel corridors for wildlife.
27 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Other BMPs detailed in the Florida silviculture BMP manual include practices for forest road planning, construction, drainage, and maintenance; stream crossings; timber harvesting; site preparation and planting; fire line construction and use; pesticide and fertilizer use; waste disposal; and wet weather operations. The BMP manual further includes specific provisions to protect wetlands, sinkholes, and canals. Associated with the BMP manual are separate forestry wildlife best management practices for state imperiled species (FDACS 2014).
Given that the Pensacola Bay watershed is substantially forested, silviculture BMPs are some of the most important tools for protecting water quality and wetland and aquatic habitat quality within the watershed. The significant relief that exists within the upper watershed (Figure 2-3) suggests application of SMZs may be particularly useful for protecting downstream aquatic habitats from further impacts.
Low Impact Development
Inclusive of green infrastructure, urban best management practices, and Florida Friendly landscaping, low impact development represents a framework for implementing innovative stormwater management, water use efficiency, and other conservation practices during site planning and development. Benefits include reduced runoff and NPS pollution, improved flood protection, and reduced erosion and sedimentation. Some specific practices include the following. Minimized effective impervious area Community greenways Vegetated swales and buffers Green roofs Bioretention cells Certification programs, such as Florida Rain gardens Water StarSM, and the Florida Green Infiltration and exfiltration systems Building Coalition
For transportation infrastructure, practices recommended to protect water quality and floodplain and wetland functions include incorporating bridge spans that accommodate bank-full stream flows while maintaining intact floodplain, wetland, and wildlife passage functions. Minimizing structural alteration of low-lying, flood-prone lands is also an important strategy for protecting water quality and providing flood protection. Such properties can be used for other purposes, such as passive parks and other public use areas.
Riparian Buffers
A riparian buffer zone is an overlay that protects an adjoining waterbody from effects of adjacent development, such as runoff, NPS pollution, erosion, and sedimentation. A buffer zone in this context refers to an area along the shoreline that is maintained in or restored to generally natural vegetation and habitat. In this condition, an intact buffer zone helps to simultaneously achieve three important goals: water quality protection, shoreline stability, and fish and wildlife habitat. Associated with these are other benefits, including aesthetic improvements and public access and recreation. These benefits are achievable for riparian areas along all types of waterbodies: stream/riverine, estuarine, lacustrine, wetlands, and karst features.
In general, the wider the buffer zone, the better these goals may be achieved, although specific requirements are defined based on community goals. Limited areas, for example, might be developed into recreational sites, trails, or other access points. Table 4-1 is a representation of generalized buffer zones, adapted from USFWS documentation, listing benefits provided by buffers of successively larger widths. Complicating buffer zone design is the fact that different sites have different ecological and physical characteristics. These characteristics (type of vegetation, slope, soils, etc.), when accounted for, would lead to different buffer widths for any given purpose. Alternatives to fixed-width buffer policies include
28 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT tiered systems that can be adapted to multiple goals and site-specific characteristics and uses. Wenger (1999) and Wenger and Fowler (2000) provide additional background, detail, and guidance for the design of buffer zone systems and policies.

Basinwide Sedimentation Abatement
Unpaved roads frequently intersect and interact with streams, creating erosion and runoff conditions that transport roadway materials directly into streams, smothering habitats and impacting water quality and the physical structure of the waterbodies. Borrow pits have also caused progressive erosion conditions that smother streams, severely damaging or destroying habitats and diminishing water quality. Existing impacts and future risks are most pronounced in the upper portion of the Pensacola Bay watershed, given the slopes and prevalent soils.
Given the site specific and physical nature of the impacts, efforts taken at the local and regional level can lead to significant restoration of aquatic habitat conditions and improved water quality. Corrective actions may include replacing inadequate culverts with bridge spans maintain floodplains and flows, hilltop-to- hilltop paving, use of pervious pavement, establishment of catch basins to treat and manage stormwater, and establishment of vegetated or terraced basins to eliminate gulley erosion.
In addition to addressing unpaved roads and gully erosion sites, application of construction BMPs, to include sediment and erosion controls, protects water and habitat quality, as well as the physical structure
29 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT of streams and other waterbodies. Extremely heavy and sustained precipitation events are common in northwest Florida; thus, for large-scale construction and transportation projects, protective BMPs are ideally capable of accommodating and preventing erosion and sedimentation during large storm systems, which frequently overwhelm conventional erosion controls.
4.1.2 Ecological Restoration
A wide array of measures may be employed to restore natural and historic functions to former or degraded wetland, aquatic, stream, riparian, and estuarine habitats. Enhancement actions, such as improving vegetation conditions, invasive exotic plant removal, and prescribed fire, are also often discussed in the context of restoration. Wetland, hydrologic, floodplain, shoreline, and stream restoration are discussed further below.
Wetland, Hydrologic and Floodplain Restoration
Wetland restoration includes actions to reestablish wetland habitats, functions, and hydrology. It frequently involves substrate composition and profile restoration and vegetation community reestablishment, including shrub reduction, exotic species removal, application of prescribed fire, and replanting.
Hydrologic and floodplain restoration include actions to reestablish pathways and the timing of surface water flow. Actions include removing fill, replacing bridges and culverts with appropriate designs, establishing low-water crossings, restoring pre-impact topography and vegetation, and abandoning unneeded roads through fill removal and replanting. Restoration activities can have broad water resource benefits, including improved water quality, enhanced fish and wildlife habitat, and other restored wetland functions.
Hydrologic restoration is important for altered wetlands and waterbodies in urbanized areas, as well as for riverine systems and for larger wetland systems. Wetland restoration, including habitat enhancements and vegetation restoration, is broadly applicable at both large and smaller scales throughout the watershed.
Shoreline Restoration
Shoreline restoration refers to measures taken to restore previously altered shorelines and to protect eroding or threatened shorelines. Such restoration is accomplished using “living shorelines” techniques, which are a set of evolving practices that incorporate intertidal and shoreline habitats to protect shorelines while also enhancing or restoring natural communities, processes, and productivity. When planned and implemented appropriately, such efforts result in direct and tangible benefits for residents and the larger community, including fish and wildlife, improved water quality, shoreline protection, and aesthetic improvements. Including biodiversity-building habitats and incorporating adjacent transitional and floodplain areas within restoration planning can increase resiliency and adaptability to anticipated changes in climate, sea levels, and shoreline configuration, as well as potential future occurrences of impacts from invasive species.
Shoreline restoration in this context is particularly applicable as a strategy along altered and/or eroding estuarine shorelines along Pensacola Bay, Escambia Bay, and East Bay. Some of the urbanized bayous may offer restoration opportunities along relatively low-energy shorelines.
30 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Stream Restoration
Stream restoration includes actions to restore the hydrology, aquatic habitat, and riparian vegetation of stream systems that may have been impacted by inadequate culverts, road crossings, instream impoundments, erosion and sedimentation, runoff or other hydrologic effects of adjacent or upstream developments. This may also include developing more natural hydrology, wetlands, storage/treatment, and riparian vegetation along stormwater conveyances. In stream restoration may include efforts to reestablish natural channel and floodplain process and should accompany efforts to address offsite processes (erosion, sedimentation, etc.) that created the original impacts.
The topographic relief within the upper watershed, as well as surrounding land uses, suggests that stream restoration may be a particularly appropriate strategy within this area. Additionally the Carpenter Creek basin and other urban drainages offer opportunities for stream restoration, often in association with stormwater retrofit and other actions.
Estuarine Habitat Restoration
Implementation of wetland and shoreline restoration, as described above, as well as aquatic habitat restoration and enhancement can be implemented in a complementary manner to improve and restore estuarine habitat and productivity. Well-established, contiguous marshes; seagrass beds; and oyster reefs provide habitat for a wide range of marine species, including recreational and commercially valuable seafood species.
Emergent marshes and oyster reefs serve as an important buffer between uplands and estuaries, filtering pollutants and consuming nutrients before they enter the water and reducing waves before they reach land. These communities promote sediment accumulation and shoreline stabilization, attenuate wave energy, protect marsh habitat, and buffer upland areas against wind and wave activity that expedite erosion. Each oyster can filter vast quantities of water, removing suspended particles that would otherwise reduce sunlight penetration needed for healthy seagrass beds.
While some recovery of seagrasses in Pensacola Bay have been observed, extensive areas of East Bay and Escambia Bay, which formerly supported seagrass, have had no recovery. Approaches to restoring seagrass habitat in the Pensacola Bay system, as identified by Yabro and Carlson (2016), include restoration of shoreline vegetation on Santa Rosa Sound to prevent further burial of vegetation, as well as investigating the extent and effects of hypoxia in the estuary and evaluating long-term effects of salinity changes on submerged aquatic vegetation in the upper reaches of the estuarine system. Results of the ongoing Roadblocks to Seagrass Recovery project may help identify strategies to facilitate recovery in these areas.
4.1.3 Wastewater Management and Treatment Improvements
Septic to Sewer Connections
Among the promising approaches for correcting impacts and impairments are actions to improve the management and treatment of domestic wastewater. While expensive and engineering-intensive, such actions are technically feasible, proven approaches to improving water quality and aquatic habitat conditions, as well as public uses and benefits.
Extending sewer service to areas that currently rely on conventional onsite treatment and disposal systems for wastewater treatment and disposal is effective in reducing nutrient loading to ground and surface water source. As outlined above, there are over 54,000 known or likely conventional septic systems in the
31 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Pensacola Bay watershed. As illustrated by Figure 3-4, these are particularly concentrated around Pensacola Bay and Santa Rosa Sound, and within their contributing basins; within the vicinities of the Blackwater, Yellow, Shoal, and Escambia Rivers; and within the Bayou Chico BMAP area. Connecting residences and businesses in these areas to centralized wastewater treatment systems has the potential to substantially improve wastewater treatment and reduce loading of nutrients and other pollutants to these waterbodies and to downstream receiving waters.
Advanced Onsite Systems
Where extension of sewer service is not economically feasible due to the spatial distribution of rural populations, there is potential for installation of advanced onsite systems that achieve water quality treatment that exceeds that provided by conventional systems. In particular, advanced passive systems are being developed to provide cost-effective and practical systems for reducing nitrogen and other pollutants from onsite sewage systems (FDOH 2015b). Pilot projects are underway in different regions of the state.
Water Reclamation and Reuse
For the purposes of this plan, water reuse refers to the application of reclaimed water for a beneficial purpose, with reclaimed water receiving at least secondary treatment and basic disinfection (Chapter 62- 10, F.A.C.; Section 373.019, F.S.). Beneficial purposes include reusing reclaimed water to offset a current or known future potable water demand or other documented watershed and water resource challenges. Specific purposes include landscape and golf course irrigation, industrial uses, and other applications (FDEP 2015f). Water reuse can be a key strategy in reducing or eliminating wastewater discharges and associated pollution of surface waters.
Centralized Wastewater Treatment Upgrade and Retrofit
For centralized wastewater treatment systems, conversion to advanced wastewater treatment has proven to be an effective means of reducing the discharge of nutrients and other pollutants into surface and ground waters. Specific treatment or process upgrades may also help improve treatment of contaminants of emerging concern, such as pharmaceuticals, surfactants, and unregulated trace chemicals. Additionally, in many areas there is a need to rehabilitate existing sewer systems, including to correct inflow and infiltration problems and to reduce the number and severity of sanitary sewer overflow incidents. Accomplishing these actions can be expensive, given the need to retrofit existing systems in often highly developed areas. Upon completion, however, notable improvements can be achieved for water quality, public recreational uses, and fisheries.
4.1.4 Land Conservation
While the Pensacola Bay watershed benefits from extensive public land areas that protect water quality and wetland and aquatic habitats and provide for public access and use, there are still opportunities to further protect water resources through the conservation of sensitive areas, including riverine, stream- front, and estuarine shorelines. Conservation can be achieved through less than fee, as well as fee simple acquisition. Additionally resource conservation can be accomplished at a sub-basin or project-level scale to augment other strategies, including stormwater retrofit and hydrologic restoration, and to provide for compatible public access and recreation.
As demonstrated through the Florida Forever program and other state, federal, local, and private initiatives, preserving sensitive lands can be an effective part of protecting water quality and habitat, as well as preserving floodplain and wetland functions. Where land is acquired fee simple by public
32 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT agencies, other benefits, such as public access and recreation, are also achieved. Resource protection can be achieved through less than fee, as well as fee simple acquisition.
4.1.5 Public Awareness and Education
Public awareness and education efforts span multiple purposes and are an essential component of many of the other actions described here. Among the purposes of awareness and education efforts are: Technical outreach to assist in implementing specific programs (for example, best management practices); Informing members of the public about the purpose and progress of implementation efforts; Providing opportunities for public engagement and participation, as well as public feedback and program accountability; and Providing broad-based educational efforts to inform members of the public and specific user groups about watershed resources, their benefits, and personal practices to ensure their protection.
Examples of educational activities include technical training for BMPs, school programs (e.g., Grasses in Classes), public events, citizen science and volunteer programs, and project site visits.
Watershed stewardship initiatives can bring together multiple partners such as federal, state, and local agencies; non-profit groups; and citizen volunteers by identifying common program goals and intended outcomes. Having a variety of participants may offer important insight and expertise, shared experiences through lessons learned, and pooling of available resources to implement projects. Specific program examples include, but are not limited to: Walk the WBIDs; Grasses in Classes; homeowner oyster gardening program; rain garden/rain barrel workshops; storm drain labeling; marina BMPs; landowner cost-share assistance programs for living shorelines; elected official information and training sessions; spring break restoration projects; and messaging through outlets such as public service announcements, social media, events, and festivals.
4.1.6 Options for Further Study and Analysis
Additional work is needed to further advance the scientific understanding of resource conditions and restoration needs and opportunities. Additional analytical work can also support improved project planning and application of innovative methods for improved resource management. Develop improved and more detailed assessments of environmental conditions and trends, to include water quality, biology, and habitat. Develop a watershed-wide NPS pollution potential assessment at the 12-digit HUC level, to include analysis of land uses, applied loading rates, and potential BMP application. Identify estuarine sites with the potential for seagrass or other benthic habitat restoration through improved water quality treatment and water management within specific contributing basins. Complete a current, basin-wide analysis and prioritization of sedimentation sources and sites, to include unpaved road stream crossings, borrow pits, gulley erosion sites, and other erosion and sedimentation sources. Develop a spatial analysis of OSTDS, to include pollutant loading estimates and estimates of potential pollutant load reduction and average receiving waterbody pollutant concentrations following connection to central sewer and/or conversion to advanced onsite systems. Delineate target areas for central sewer connections and for advanced onsite systems.
33 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Develop a hydrodynamic model to improve the understanding of estuarine circulation, with application for estuarine and littoral restoration planning. Develop updated, regionally specific storm surge, floodplain, and sea level rise models to support project planning, floodplain protection, and adaptation planning, and to further the understanding of drivers of coastal habitat change. Evaluate the feasibility and potential benefits of proposed innovative and large-scale projects. Also identify and evaluate the potential for unintended adverse effects. Examples of such projects may include, but are not limited to: Pumped and tidal flow-through circulation systems Regional-scale shoreline habitat development proposals Stream channel reconfiguration Dredged material removal and disposal Benthic dredging Develop improved metrics for monitoring and evaluating projects, programs, and environmental conditions and trends. Develop proposed scope of work, for multi-agency and peer evaluation, to address PCB contamination within Escambia Bay. Evaluate integrated water resource management approaches with application to specific water resource challenges in northwest Florida, potentially further developing plans for the reuse of reclaimed water and stormwater harvesting. Evaluate the extent and effects of seasonal hypoxia and the long-term effects of salinity change on submersed aquatic vegetation in the upper portions of the estuary. Develop analysis of oyster/shellfish habitat, conditions, and trends. Establish a framework for detecting the effects of climate change and ocean acidification on coastal marine resources in the region. Conduct monitoring and evaluate potential effects of herbicides, pharmaceuticals, endocrine disruptors, and other contaminants that have received relatively little historical attention in the Pensacola Bay system. Review past projects completed, identifying specific outcomes and lessons learned. Identify locally sensitive indicators of biological condition (biocriteria) for dominant diversity- building habitats (tidal wetlands, oyster reefs, and seagrass). Conduct future analysis within areas of the bay system with more limited environmental databases, such as East and Blackwater bays and Bayou Grande. Develop updated baseline study of current environmental conditions by conducting a one-time, multi- seasonal, multi-metric, and system-wide environmental analysis. Develop online consolidation of past and present environmental information, including natural resource coverages, research activities, restoration progress, monitoring results, TMDL updates, and regulatory actions.

57 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT 4.4 Project Criteria and Guidelines
This section outlines recommended guidelines to be applied to project development and prioritization. These items are not intended to be pass-fail for projects, but rather identify provisions that should receive consideration in project development and evaluation. Criteria specific to any given prioritization or funding decision are often defined, at least in part, by the funding resources under consideration. Individual sources of funding often are guided by criteria and guidelines established by statute or program documentation.
Generally suggested criteria for project evaluation are as follows.
1. Projects with responsible parties that will implement, operate, and maintain the completed facilities should be given priority consideration. Responsible parties optimally have dedicated sources of funding that will facilitate long-term operation and maintenance. Examples may include stormwater utilities and local option sales taxes. 2. Restoration that is substantially self-sustaining should be considered. Optimally, funded projects should not require continual or frequent human intervention beyond basic maintenance. 3. Responsible parties should support long-term monitoring to facilitate verification, lessons learned, and adaptive management. Long-term monitoring is also beneficial to support verification, lessons learned, and adaptation. 4. For restoration projects, sites and systems should be selected such that they reflect and are adaptable to natural variability. Restored habitats, for example, should be adaptable to cyclic climatic conditions (e.g., seasonal, hydrologic), discrete events (e.g., coastal storms), and long-term changes in the environment (e.g., climate change and sea level rise). 5. Cost effectiveness, technical feasibility, and regulatory factors are criteria to be considered in any prioritization and funding decision.

In addition to the projects listed above, local governments and state and regional agencies have completed a number of initiatives and projects that directly correspond to and advance SWIM plan implementation. Several of the more prominent efforts are described below. Other related resource management activities are described in Appendix B.
Escambia County Dirt Road Project – With U.S. EPA 319(h) program funding, Escambia County evaluated alternative pavements for unpaved roads and implemented paving projects to reduce sediment erosion and runoff to streams. Work was completed in 2011 (Fabre Engineering and Surveying 2016).
Big Escambia Creek Restoration – About 40 years ago, a major storm rerouted the Big Escambia Creek from its original braided streams and floodplain through a series of sandpits. The new channel lacked a floodplain and stable riparian areas, thus, allowing increased velocity and sedimentation. The sedimentation impacts reached several miles downstream into the Escambia River. The USACE, in
A-3 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT partnership with the states of Alabama and Florida, the NWFWMD, Three Rivers Resource Conservation and Development Council, and the Alabama Rural Development Council, completed a large-scale project that restored the creek back to its natural channel within the wetland floodplain (FDEP 2009).
Project Greenshores – Two habitat restoration projects on the north shore of Pensacola Bay created salt marsh, seagrass, and oyster reef habitat along the shoreline. It is a partnership between the FDEP’s Northwest District Office Ecosystem Restoration Section, the City of Pensacola, the Ecosystem Restoration Support Organization, federal and local agencies, businesses, and community volunteers. The first habitat restoration site (Site I) provides eight acres of salt marsh habitat and seven acres of oyster reef. The second site (Site II), when completed, will provide an additional 14 acres of salt marsh and 13 acres of oyster reef habitat. Project Greenshores received the Coastal America Partnership Award for its extensive community involvement (FDEP 2016g).
City of Pensacola Transportation/Stormwater Plan Projects – Numerous stormwater retrofits, reconstruction, drainage improvements, and other projects have been completed, as follows (City of Pensacola 2016): o Government Street Regional Stormwater Pond; o Guillemard Street Storm Sewer Reconstruction o Long Hollow/Cervantes Street Stormwater Pond o Carpenter Creek Retrofit o 17th Avenue Park and Drainage Improvement o Sewell Street Stormwater Drainage Easement Acquisition o Chipley Street Drainage Improvement o L and Zarrogossa Street Drainage Improvement o Government Street/Jones Park Drainage Improvement o Zarrogossa and C Street Drainage Improvement o 9th Avenue Baars Drainage Improvement o Sanders Beach Storm Sewer Reconstruction o Longhollow Pond Reconstruction o 9th Avenue and Texar Drainage Improvement o Burgess Road and Sanders Drainage Improvement o Carpenter Creek/Bayou Texar stormwater management assessment o East Hill Drainage Improvement
Bayou Chico Restoration Projects – Over the past 20 years, several water quality improvement projects have been undertaken by the FDEP’s Northwest District Ecosystem Restoration Section, Escambia County, NWFWMD, and Bayou Chico Association. Projects include the removal of the old Barrancas Street drawbridge, removal of the old CSX train trestle, construction of a sediment basin at W Street, construction of the Maggie’s Ditch stream restoration, and several emergent marsh restoration projects along the bayou’s shoreline.
Wayside Park Restoration Project – The City of Gulf Breeze, FDEP, and the USACE constructed an offshore rock breakwater and seagrass/emergent marsh at the south end of Three Mile Bridge (FDEP 2007).
Deadman’s Island Restoration Project – With funding assistance from the U.S. Army Corps of Engineers, the City of Gulf Breeze completed restoration of approximately 13 acres of littoral habitat, including an oyster reef breakwater and salt marsh (Reed 2017). The project included demonstration and evaluation of alternative restoration techniques and accomplished protection of habitats affected by historical bridge construction, dredging, and shoreline armoring.
A-4 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT Appendix B Related Resource Management Activities
Much of the progress to date is attributable to cooperative efforts made on the part of local governments; state, federal, and regional agencies; and private initiatives. Many programs and projects share common goals, and their implementation is most frequently accomplished through coordinated planning, funding, management, and execution. This section describes historical and ongoing activities and programs to address resource issues within the watershed.
Special Resource Management Designations
Outstanding Florida Waters
The FDEP designates Outstanding Florida Waters (OWFs) under section 403.061(27), F.S., which are then approved by the Environmental Regulation Commission. An OFW is defined by FDEP as a waterbody “…worthy of special protection because of its natural attributes.” A number of waterbodies and segments in the watershed have been recognized and receive additional regulatory protection through designation as OFWs, per Section 62-302.700, F.A.C. Designated OFWs include: Yellow River Marsh Aquatic Blackwater River State Park Preserve Yellow River Marsh Preserve Fort Pickens Aquatic Preserve State Park Gulf Islands National Seashore Clear Creek between Milton and Escambia Bay Bluffs Whiting Field
Aquatic Preserves
Florida currently has 41 aquatic preserves, encompassing approximately 2.2 million acres of submerged lands protected for their biological, aesthetic, and scientific value. As described in Chapter 18-20, F.A.C., aquatic preserves were established for the purpose of being preserved in an essentially natural or existing condition so that their aesthetic, biological, and scientific values may endure for the enjoyment of future generations. The Pensacola Bay system includes two aquatic preserves: the Yellow River Marsh Aquatic Preserve, and the Fort Pickens Aquatic Preserve.
The Yellow River Marsh Aquatic Preserve encompasses approximately 11,000 acres of the Yellow River, Blackwater Bay, and East Bay. The aquatic preserve is among the watershed’s least impacted natural areas and includes more than 3,000 acres of salt and freshwater marshes and approximately 5,000 acres of forested wetlands. The remainder of the preserve is open water. Eglin AFB and the NWFWMD manage almost half of the uplands adjacent to the preserve, which further protects water quality (FDEP 2016f).
Fort Pickens Aquatic Preserve includes 34,000 acres of submerged lands adjacent to Gulf Islands National Seashore. The preserve includes sandy bottom and seagrass bed habitats that are for numerous species, including the loggerhead turtle (Caretta caretta), the southeastern snowy plover (Charadrius nivosus), the least tern, and the black skimmer (Rynchops niger). Fort Pickens Aquatic Preserve includes portions of Santa Rosa Sound, Pensacola Bay, and Big Lagoon, extending northward to the Gulf Intracoastal Waterway. The preserve also includes submerged lands in the Gulf of Mexico up to three miles south of the coastline (FDNR 1992).
B-1 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Conservation Lands
Approximately 520,000 acres, or 35 percent, of the watershed in Florida consists of public and conservation lands. These are listed with short descriptions in Appendix G.
The NWFWMD owns and manages over 55,000 acres within the watershed. The Yellow River, Escambia River, Blackwater River, and Garcon Point WMAs are public lands that provide joint conservation and recreational use. The District also manages 19 acres in the watershed as conservation easements, maintaining private ownership while protecting water resources. The Yellow, Blackwater, and Escambia River WMA tracts are also managed by FWC as Wildlife Management Areas. These areas are managed to protect and restore wildlife habitat, while also providing a resource for compatible public recreation. Land-management activities include prescribed burning, timber management, groundcover restoration, reforestation, and other activities (FWC 2016d, NWFWMD 2016b). The FWC also manages the Lake Stone Fish Management Area in Escambia County.
Source: FDEP 2011b; FNAI 2016b Figure B-1 Conservation Lands within the Pensacola Bay Watershed
The National Park Service owns and manages the Gulf Islands National Seashore, established in 1971. The seashore supports an abundance of natural habitats, including coastal dunes, scrub, and estuarine marsh ecosystems. Portions of the military lands within the watershed are managed as conservation areas, including 10,738 acres owned and managed by the U.S. Navy and 229,743 acres owned and managed by the U.S. Air Force (FNAI 2010).
State lands in the watershed include the Blackwater River State Forest, Fort Pickens State Park, and Blackwater River State Park. The Blackwater River State Forest covers over 210,000 acres in northern Santa Rosa and Okaloosa counties, including significant portions of the Blackwater River and Yellow
B-2 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
River watersheds. These park and forest lands protect water and other natural resources, while also providing important opportunities for public use and recreation. The state forest is also a resource for timber production, with harvesting following silvicultural BMPs.
Garcon Peninsula Mitigation Bank and Pensacola Bay Mitigation Bank are privately owned wetland mitigation banks within the Pensacola watershed. The Pensacola Bay Mitigation bank consists primarily of mixed hardwood and pine flatwoods and hosts a healthy population of carnivorous pitcher plants, while Garcon Peninsula Mitigation Bank consists primarily of pitcher plant prairie (Garcon Peninsula Mitigation Bank, LLC 2001; Westervelt Ecological Services 2016). The Garcon Peninsula Mitigation Bank is northwest Florida's first wetlands mitigation bank and includes over 330 acres within the watershed (FNAI 2010, 2016a).
Jones Swamp Preserve was purchased by Escambia County in 1996 as part of Bayou Chico restoration efforts to provide buffering and protection of water quality in the Pensacola Bay area. The Jones Swamp Wetland Preserve consists of over 580 acres within the Jones Creek watershed, at the urban interface within the Bayou Chico drainage (Escambia County 2016a). More than 60 percent of the Jones Swamp Preserve is covered by forested wetlands, including hardwood swamp, bay swamp, cypress swamp, and mixed wetland forest communities. The Preserve is managed for wetland, groundwater, and surface water quality protection and restoration; hydrological restoration, including floodplain restoration; preservation and conservation of natural resources; environmental education; and outdoor recreation.
Critical Habitat and Strategic Habitat Conservation Areas
The Pensacola Bay system sustains numerous listed species, as designated under the Endangered Species Act (ESA). The ESA also provides special protection for Critical Habitat of certain species, which may include an area that is not currently occupied by the species, but that will be needed for its recovery.
As described above, the Pensacola Bay system includes federally designated critical habitat for the threatened Gulf sturgeon and several species of freshwater mussels. The watershed also supports the threatened piping plover, the endangered reticulated flatwoods salamander, and the blackmouth shiner, which is considered endangered by the state of Florida (FNAI 2001).
Certain natural areas within the watershed have been identified by the FWC as Strategic Habitat Conservation Areas (SHCAs). SHCAs are important habitats in Florida that do not have conservation protection, which would increase the security of rare and imperiled species if they were protected. Within the Pensacola Bay watershed, SHCAs have been identified for several species, including the Florida black bear (Ursus americanus floridanus), pine barrens tree frog (Hyla andersonii), seal salamander (Desmognathus monticola), and others (Endries et al. 2009)
Portions of the estuary adjacent to the Gulf of Mexico also provide habitat for three species of threatened and endangered sea turtles, and beach and dune communities alo provide habitat for the endangered Santa Rosa Beach mouse (Peromyscus polionotus leucocephalus) (USFWS 2016a).
The FDACS publishes a list of the protected plants of Florida, including those species listed as federally threatened and endangered by the USFWS (Weaver and Anderson 2010). The table in Appendix D provides a list of species that are protected for the watershed, as well as their habitat requirements.
Gulf Ecological Management Sites
The watershed includes two Gulf Ecological Management sites (GEMS), the Yellow River Marsh Fort Pickens aquatic preserves. The GEMS Program is an initiative of the Gulf of Mexico Foundation, the
B-3 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
EPA Gulf of Mexico Program, and the five Gulf of Mexico states (Gulf of Mexico Foundation 2015). Designated GEMS are considered high priority for protection, restoration, and conservation by state and federal authorities due to unique ecological qualities such as habitats significant to fish, wildlife, or other natural resources (Gulf of Mexico Foundation 2015).
Deepwater Horizon: RESTORE Act, Natural Resource Damage Assessment (NRDA), and NFWF Projects
The FDEP and the FWC are the lead state agencies in Florida for responding to the impacts of the Deepwater Horizon oil spill and the resulting restoration process. Restoration projects submitted through the FDEP are considered for funding under the Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast Act (RESTORE Act) Comprehensive Plan Component, the NRDA, and the NFWF’s GEBF.
RESTORE
The RESTORE Act of 2012 allocates to the Gulf Coast Restoration Trust Fund 80 percent of the CWA administrative and civil penalties resulting from the oil spill. The major means of allocation under the RESTORE Act are as follows:
Direct Component Funds (“Bucket 1”): Seven percent of these funds will be directly allocated to counties affected in Florida (5.25 percent to the eight disproportionately affected counties in the Panhandle from Escambia to Wakulla counties; and 1.75 percent to the non-disproportionately impacted Gulf Coastal counties). To receive funds under the Direct Component, each county is required to submit a Multiyear Implementation Plan, subject to review by the U.S. Department of the Treasury, detailing the county’s plan to expend funds for a set of publically vetted projects and goals (FDEP 2016h).
Comprehensive Plan Component (“Bucket 2”): A portion of RESTORE funds will go toward projects with a wider geographic benefit (multiple states). These projects are selected by the Gulf Coast Ecosystem Restoration Council, which includes the five Gulf States and six federal agencies. Projects can be submitted by the Council members and federally recognized Native American tribes.
Spill Impact Component (“Bucket 3”): Each of the five Gulf states will receive these funds to implement a State Expenditure Plan. In Florida, this plan is being developed through the Gulf Consortium, which was created by inter-local agreement among Florida’s 23 Gulf Coast counties. Projects will be submitted by each of the 23 counties on Florida’s Gulf Coast.
National Resource Damage Assessment (NRDA)
The Oil Pollution Act of 1990 authorizes certain state and federal agencies to evaluate the impacts of the Deepwater Horizon oil spill. This legal process, known as NRDA, determines the type and amount of restoration needed to compensate the public for damages caused by the oil spill. The FDEP, along with the FWC, are co-trustees on the Deepwater Horizon Trustee Council.
National Fish and Wildlife Foundation
The National Fish and Wildlife Foundation (NFWF) established the GEBF to administer funds arising from plea agreements that resolve the criminal cases against BP and Transocean. The purpose of the GEBF, as set forth in the plea agreements, is to remedy harm and eliminate or reduce the risk of future harm to Gulf Coast natural resources. The plea agreements require NFWF to consult with state and
B-4 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT federal resource agencies in identifying projects. The FWC and the FDEP work directly with the NFWF to identify projects for the state of Florida, in consultation with the USFWS and the NOAA. From 2013 to 2018, the GEBF will receive a total of $356 million for natural resource projects in Florida. However, the allocation of funds is not limited to five years. NFWF funded the development of the 2017 SWIM plan updates through the GEBF.
The Nature Conservancy (TNC): Watershed Management Planning
To achieve comprehensive and long-term success for Gulf restoration, TNC facilitated a community- based watershed management planning process in 2014 and 2015 along Florida’s Gulf Coast for the following six watersheds: Perdido Bay, Pensacola Bay, Choctawhatchee Bay, St. Andrew and St. Joseph bays, Apalachicola to St. Marks, and the Springs Coast. The process was designed to develop watershed- based plans that identify environmental issues affecting each watershed and solutions that address the issues. The process was also intended to create long-term partnerships among stakeholders in each watershed and across the regions to maximize effectiveness of project implementation and funding efforts and to provide a screening tool to evaluate priorities for potential funding (TNC 2014).
The TNC Plan developed for the Pensacola Bay system identifies 43 separate projects to address seven major actions (TNC 2014): Protect, restore, create and/or manage natural habitat and resources and increase buffer areas; Increase cooperation and coordination for management, monitoring, funding, implementation, outreach, and enforcement; Reduce impacts to groundwater and ensure adequate fresh water availability; Reduce and treat stormwater; Reduce nutrient loading; Reduce sedimentation; and Increase economic diversification.
To complete the planning process and ensure that all of the priority issues are identified and addressed, the plan recommended updating the 1997 Pensacola Bay System SWIM Plan (TNC 2014).
Monitoring Programs
The majority of the monitoring data in the Pensacola Bay system, including chemical and biological data, has been collected by the FDEP Northwest District staff and the Bream Fishermen Association (BFA) (FDEP 2007). Data-gathering activities include working with environmental monitoring staff in the NWFWMD and local and county governments to obtain applicable monitoring data from their routine monitoring programs and special water quality projects in the basin. All of the data collected by the FDEP and its partners is uploaded to the statewide water quality database for assessment.
Several water quality monitoring programs are ongoing in the watershed. These include the FDEP Trend and Status Networks; FDACS Shellfish Environmental Assessment Section (SEAS); the FDOH Florida Healthy Beaches monitoring program; and the BFA.
The following subsections provide an overview of these programs and some of their relevant findings.
FDEP/NWFWMD
Long-term trends in water quality are monitored by FDEP’s Surface Water Temporal Variability (SWTV) and Groundwater Temporal Variability (GWTV) monitoring networks. These are statewide networks of
B-5 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT fixed sites selected to reflect the water quality impacts across the state. The SWTV network includes data collection at 78 fixed sites, including seven sites in the Pensacola Bay system (FDEP 2016j, 2016k): Escambia River – two sites: one in Century, near the Alabama-Florida state line, and one downstream at a site that is representative of the watershed’s land use activities. Blackwater River – two sites: one in the upstream, undeveloped portions of the river. And one on Big Coldwater Creek, a tributary of the Blackwater River. Yellow River – two sites: one near the Alabama-Florida state line, and one downstream, near East Bay, at a site that is representative of the watershed’s land use activities. East Bay River – one site near East Bay that is representative of the watershed’s land use activities.
Parameters monitored include color alkalinity, turbidity, suspended and dissolved solids, nutrients, total organic carbon, chlorides, sulfate, metals (calcium, potassium, sodium, magnesium), pH, conductivity, temperature, DO, total coliform bacteria, fecal coliform bacteria, enterococci bacteria, and Escherichia bacteria (FDEP 016i, 2016j).
The GWTV network includes data collection at 49 fixed stations statewide (24 unconfined aquifer wells, 23 confined aquifer wells, and two spring vents), including one unconfined aquifer well sampled monthly, located north of Bayou Grande and the Pensacola NAS.
Water quality data are maintained and made available through the Storage and Retrieval (STORET) database.
FDEP Northwest District
The FDEP’s Northwest District has collected considerable biological data and conducted biological evaluations of numerous stream and other aquatic habitat sites throughout the watershed (FDEP 2007). The biological data collected by the FDEP Northwest District includes Stream Condition Index, Stream Habitat Assessment, Stream Linear Vegetation Index, Stream Rapid Periphyton Survey, Wetland Condition Index, and Bioassessment data, all are reported and accessible via STORET.
Florida Department of Agriculture and Consumer Services
To minimize the risk of shellfish-borne illness, FDACS continually monitors and evaluates shellfish harvesting areas and classifies them accordingly. It also ensures the proper handling of shellfish sold to the public. Under the SEAS program, FDACS collects and analyzes data from 1,200 bacteriological sampling stations in 39 shellfish harvesting areas encompassing 1.4 million acres in Florida, including five shellfish harvesting areas in the Pensacola Bay system. The FDACS monitors bottom and surface temperature, salinity, DO, surface pH, turbidity, fecal coliform bacteria, water depth, and wind direction and speed at monitoring stations in Pensacola Bay, Escambia Bay, East Bay, East Bay River, and Blackwater Bay. The dataset begins in 1985 and continues to the present. These stations are monitored at least monthly and often more frequently (FDACS 2016b).
The FDEP identified eight waterbody segments as verified impaired for bacteria in the Pensacola Bay watershed, based on shell fish classifications issued by the FDACS (see Section 3.2).
Florida Department of Health
The Florida Healthy Beaches Program was initiated by the FDOH as a pilot beach monitoring program in 1998 with expansion to include all the state’s coastal counties in August 2000 (FDOH 2005). The
B-6 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Escambia County and Santa Rosa County health departments participate in the program with weekly monitoring of beaches for enterococcus and fecal coliform bacteria at 14 local beaches. County health departments issue health advisories or warnings when bacterial counts are excessive (FDEP 2007). Beaches with more than 21 closures in a year are identified as impaired by FDEP.
Bream Fishermen Association
The Bream Fishermen Association (BFA) is an organization of local fishermen and residents that assists the city, county, state, and region as an environmental steward in protecting northwest Florida and south Alabama waters by performing regular water quality monitoring. The BFA was established in the mid- 1960s and was chartered as a non-profit organization in 1970. Today, the BFA collects samples at 48 quarterly stations in Escambia, Santa Rosa, and Okaloosa counties (BFA 2016).
Submerged Aquatic Vegetation Monitoring
In the late 1990s, FDEP Northwest District’s Ecosystem Restoration Section conducted a study to monitor the health of seagrasses in Big Lagoon and Santa Rosa Sound. The study concluded with a management plan, which included recommendations for improving the health of SAVs in the study area (FDEP 2001). The USGS published a report on the status and trends of seagrasses along the Gulf Coast, including the Pensacola Bay system (USGS 2006). The FWC’s FWRI currently evaluates changes in the extent, density, and quality of seagrasses in Pensacola Bay, Big Lagoon, and Santa Rosa Sound as part of the statewide SIMM program. The maps are generated through photointerpretation of high-resolution imagery. The general status of seagrasses for the bays is discussed in Section 3.3.1 (FWC 2015c).
Environmental Restoration and Protection Programs
Water quality in the Pensacola Bay watershed is protected through several programs working together to restore water quality and prevent degradation. These programs include FDEP’s adopted TMDLs; BMPs for silviculture, agriculture, construction, and other activities related to land use and development; regulatory programs including NPDES, domestic and industrial wastewater permits, stormwater permits, and ERP; and local efforts to retrofit stormwater infrastructure to add or improve water quality treatment. Additionally, water quality is protected through a number of conservation, mitigation, and management programs that protect water resources, aquifer recharge areas, floodplains, and other natural systems within the watershed. These programs include Florida Forever Work Plan, regional mitigation for state transportation projects, and spring protection and restoration. The following section provides an overview of these programs and their contribution to water quality restoration and protection.
Total Maximum Daily Loads
As described above, TMDLs are developed for waterbodies that are verified as not meeting adopted water quality standards to support their designated use. They provide important water quality restoration goals to guide restoration activities. They identify the reductions in pollutant loading required to restore water quality. Total daily maximum loads are implemented through the development and adoption of BMAPs that identify the management actions necessary to reduce the pollutant loads. Basin Management Action Plans are developed by local stakeholders (public and private) in close coordination with FDEP. Although water segments with adopted TMDLs are removed from the state’s impaired waters list, they remain a high priority for restoration. Impaired waters and TMDLs are described in greater detail in Chapter 3 and Appendix F.
B-7 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT National Pollutant Discharge Elimination System Permitting
Point sources that discharge to surface waterbodies require a National Pollutant Discharge Elimination System (NPDES) permit. These permits can be classified into two types: domestic or industrial wastewater discharge permits, and stormwater permits. An NPDES permit includes limits on the composition and quantity of a discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does cause pose a threat to human health or quarter quality. All NPDES permits include “reopener clauses” that allow the FDEP to incorporate new discharge limits when a TMDL is established. These new limitations may be incorporated into a permit when a TMDL is implemented or at the next permit renewal, depending on the timing of the permit renewal and workload. For NPDES municipal stormwater permits, the FDEP will insert the following statement once a BMAP is completed (FDEP 2007): The permittee shall undertake those activities specified in the (Name of Waterbody) BMAP in accordance with the approved schedule set forth in the BMAP.
The FDEP implements the NPDES stormwater program in Florida under delegation from the EPA. The program requires the regulation of stormwater runoff from MS4s generally serving populations of more than 10,000 and denser than 1,000 per square mile, construction activity disturbing more than one acre of land, and ten categories of industrial activity. An MS4 can include roads with drainage systems, gutters, and ditches, as well as underground drainage, operated by local jurisdictions, the FDOT, universities, local sewer districts, hospitals, military bases, and prisons. Escambia County, Pensacola, and Century are Phase 1 co-permittees with the FDOT District 3. Stormwater management for other local governments, military bases, and educational institutes within the Pensacola Bay system is covered under Phase 2 MS4 permits. Phase 2 permits are general permits and are not written for a specific local government. Phase 2 permit holders in the Pensacola Bay system include: Pensacola NAS, Eglin AFB, Hulbert Field (U.S. Air Force), University of West Florida, Okaloosa and Santa Rosa counties, and the cities of Niceville, Gulf Breeze, and Milton (FDEP 2007).
As part of the MS4 program, Escambia County’s Stormwater Program has delineated the county into 41 drainage basins. The basins have been numerically ranked based on the severity of water quality and drainage issues to establish an order of priority for remediation. A countywide Stormwater Master Plan has been completed (Hatch Mott MacDonald 2004). Countywide drainage plans have either been completed or are under way for 23 individual drainage basins. Each plan describes current stormwater structural controls and identifies and recommends water quality and drainage improvement projects. Funding for stormwater retrofits is provided by a local option sales tax, which was approved by Escambia County voters in 1992. The intent of the tax is to help pay for capital improvement projects that address flooding, improve access to residential and commercial properties (improve transportation), and improve stormwater quality. It became effective June 1, 1992, and was renewed by a voter referendum in 1999. It was reapproved by voters in 2008 and will be in effect until December 31, 2017. Revenue generated by the tax has provided money to pave dirt roads and improve drainage and transportation. As of February 2003, $37.3 million had been spent for projects to primarily improve drainage, $28.4 million to primarily improve transportation, and $16.2 million to pave dirt roads (Hatch Mott McDonald 2004).
Domestic and Industrial Wastewater Permits
In addition to NPDES-permitted facilities, all discharge to surface waters, Florida also regulates domestic and industrial wastewater discharges to groundwater via land application. Since groundwater and surface water are so intimately linked in much of the state, reductions in loadings from these facilities may be needed to meet TMDL limitations for pollutants in surface waters. If such reductions are identified in the BMAP, they would be implemented through modifications of existing state permits.
B-8 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT Best Management Practices
Best management practices may include structural controls (such as retention areas or detention ponds) or non-structural controls (such as street sweeping or public education). Many BMPs have been developed for urban stormwater to reduce pollutant loadings and peak flows. These BMPs accommodate site- specific conditions, including soil type, slope, depth to groundwater, and the use designation of receiving waters (such as drinking water, recreation, or shellfish harvesting).
The passage of the 1999 Florida Watershed Restoration Act (Chapter 99-223, Laws of Florida) increased the emphasis on implementing BMPs to reduce NPS pollutant discharges from agricultural operations. It authorized the FDEP and the FDACS to develop interim measures and agricultural BMPs. While BMPs are adopted by rule, they are voluntary if not covered by regulatory programs. If they are adopted by rule and the FDEP verifies their effectiveness, then implementation provides a presumption of compliance with water quality standards, similar to that granted a developer who obtains ERP (FDACS 2016c).
Over the last several years, the FDACS has worked with farmers, soil and water conservation entities, the University of Florida’s Institute of Food and Agricultural Sciences, and other interests to improve product marketability and operational efficiency of agricultural BMPs, while at the same time promoting water quality and water conservation objectives. In addition, programs have been established and are being developed to create a network of state, local, federal, and private sources of funds for developing and implementing BMPs. BMPs have been adopted by rule for silviculture, row crops, container plants, cow calf, and dairies. The BMP manuals can be accessed on the FDACS website (FDACS 2016c).
Florida Environmental Resource Permitting Program
Florida established the Environmental Resource Permitting (ERP) program to prevent stormwater pollution of Florida’s rivers, lakes, and streams, and to protect wetland functions and provide flood protection. The ERP program regulates the management and storage of surface waters and provides protection for the vital functions of wetlands and other surface waters. Environmental resource permits are designed to obtain 80 percent average annual load reduction of total suspended solids. In northwest Florida, the ERP program is jointly implemented by the NWFWMD and the FDEP.
Regional Mitigation for State Transportation Projects
Under Section 373.4137, F.S., the NWFWMD offers mitigation services, as an option, to the FDOT for transportation projects with unavoidable wetland impacts when the use of private mitigation banks is not feasible. As required by this statute, a regional mitigation plan has been developed and is updated annually to address FDOT mitigation needs submitted to the NWFWMD. Components of the Umbrella Plan include the federally permitted “In-Lieu Fee Program” instrument and other mitigation projects (NWFWMD 2016a). The District does not compete with private mitigation banks. The District’s mitigation plan is developed and implemented in consultation with the FDOT, the FDEP, the USACE, the EPA, the USFWS, the U.S. National Marine Fisheries Service, and the FWC and is maintained and available for review at http://www.nwfwmdwetlands.com/.
Since 1997, the NWFWMD has implemented mitigation at seven sites in the Pensacola Bay system: Bluff Springs, Brewer, Cotton Creek Road, Jones Swamp, Mystic Springs, Rogers, and Yellow River Ranch (NWFWMD 2016c).
B-9 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT FDEP Ecosystem Restoration Section
The FDEP (through funding from the USFWS Coastal Program and other sources) has established living shoreline restoration sites within the Pensacola Bay system to aid in shoreline stabilization, biodiversity, and water quality (FDEP 2015e). Living shorelines are constructed of oyster shells, limestone rock, or other substrate conductive to the natural environment. These created shorelines provide a physical barrier for the mainland during storms, and aid in sediment stabilization through the use of planted native vegetation (FDEP 2015e).
Florida Forever
Florida Forever is Florida’s conservation and recreation lands acquisition program. Under section 373.199, F.S., and the NWFWMD Florida Forever 2016 Five Year Work Plan, a variety of projects may be implemented, including capital projects, land acquisition, and other environmental projects. Since its inception, the District’s land acquisition program has sought to bring as much floodplain as possible of the major rivers and creeks under public ownership and protection. The District’s Florida Forever Five Year Plan identifies land acquisition priorities along the Escambia River, Garcon Point Peninsula, the Blackwater River, and the Yellow River. Additional information is available at http://www.nwfwater.com/Lands/Land-Acquisition/Forever-Florida-Land-Aquisition-Work-Plans.
Minimum Flows and Minimum Water Levels
Section 373.042, F.S., requires each water management district to develop minimum flows and minimum water levels (MFLs) for specific surface and groundwaters within their jurisdiction. A minimum flow or minimum water level for a given waterbody is the limit below which further withdrawals would be significantly harmful to the water resources or ecology of the area. Minimum flows and minimum water levels are calculated using best available data and consider natural seasonal fluctuations; non- consumptive uses; and environmental values associated with coastal, estuarine, riverine, spring, aquatic, and wetlands ecology as specified in Section 62-40.473, F.A.C.
The process of establishing MFLs involves a series of steps including identification of priority waterbodies, data collection, technical assessments, peer review, rule-making and rule adoption. Adopted MFLs are considered when reviewing consumptive use permit applications. A recovery or prevention strategy must be developed for any waterbody where consumptive uses are currently or anticipated to result in flows or water levels below adopted MFLs.
A technical assessment for an MFL for the Floridan aquifer, Coastal Region II, in Santa Rosa, Okaloosa, and Walton counties was initiated in 2014. The Shoal River system MFL technical assessment was initiated in 2017. The current status of planning and development of MFLs in northwest Florida may be found at http://www.nwfwater.com/Water-Resources/Minimum-Flows-Levels.
EPA Gulf Ecology Division
The EPA, Gulf Ecology Division Laboratory in Gulf Breeze, Florida, is a primary research facility of the EPA’s Office of Research and Development National Health and Environmental Effects Research Laboratory. The lab assesses the ecological condition, ecological services and values of estuaries, coastal wetlands, seagrass, and coral ecosystems of the Gulf of Mexico and the southeastern U.S.; determines causes of ecological impairment; predicts future risk to populations, communities and ecosystems from multiple aquatic stressors; supports the development of criteria to protect coastal environments; and transfers scientific technology to federal and state agencies, industry, and the public (EPA 2016f).
B-10 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT Natural Resource Management at Eglin AFB
The U.S. military, represented by the Air Force at Eglin AFB and Hurlburt Field, and the Navy at NAS Pensacola and NAS Whiting Field, occupies about 241,000 acres in the Pensacola Bay system. Eglin AFB is the largest forested military reservation in the U.S. and provides habitat for numerous rare and endangered species, including the red-cockaded woodpecker and reticulated flatwoods salamanders. The AFB spans 20 miles of the Gulf of Mexico shoreline, and includes 55 acres of lakes and 186 miles of streams. The property also hosts 34 of the FNAI recognized natural communities (FWC 2016e; Secretary of Defense 2013). Consequently, management actions on Air Force property have the potential to substantially influence water and habitat quality at the scale of the drainage basin.
Large tracts of Eglin AFB are managed for habitat conservation and the protection of endangered species. Extensive tracts of mature longleaf pine (Pinus palustris) forest are still present, particularly in the Conecuh National Forest–Blackwater River State Forest–Eglin AFB corridor (FDEP 2007).
Since 2009, TNC and Eglin AFB, with funding from the Legacy Program, have worked with military bases in Florida to establish six Cooperative Invasive Species Management Areas (CISMAs). These CISMAs are designed to help to decrease the re-infestation from invasive species at six Florida bases (U.S. Department of Defense [DOD] 2011). As a result of this initiative, a report called Utilizing Cooperative Invasive Species Management Areas (CISMAs) to Effectively Reduce Re-infestation of Invaders on Six (6) Military Bases and Adjacent Lands in Florida was developed. The report details the development of the CISMAs, their accomplishments, project monitoring, and strategic plans.
About 404,000 acres of Eglin AFB are managed under the Integrated Natural Resources Management Plan, which is updated every five years and is signed by Eglin, the FWC, and the USFWS. Additionally, Eglin AFB’s Jackson Guard maintains an interactive web-based Integrated Natural Resources Management Plan that functions as an adaptive management tool (Secretary of Defense 2013). In 2013, Eglin’s Natural Resources Team exceeded the goal of rehabilitating wetland riparian and 20 threatened and endangered species sites as specified in the Integrated Natural Resources Management Plan Erosion Control Component Plan. Other ongoing initiatives at the AFB include fish and wildlife management, invasive species control and pest management, and forest management using prescribed fires and other BMPs (Secretary of Defense 2013).
Bay Area Resource Council
The Bay Area Resource Council (BARC) was created from the Escambia/Santa Rosa Coast Resource Planning and Management Committee in 1985 by then Governor Bob Graham. An interlocal agreement between Escambia and Santa Rosa counties and the cities of Pensacola and Gulf Breeze was established in May 1987 to establish an entity that could accept funding and promote the goals of the committee. The City of Milton has since joined the BARC. Advisory committees for citizens and scientists were established to begin the development of a management plan for the Pensacola Bay system. The Pensacola Bay Watershed Management Guide, completed in 1998, contained 50 action plans. The BARC Technical Advisory Committee completed an update of the plan in late 2004 (Pensacola Bay Watershed Partnership and BARC 2005). The BARC’s goal is improving the area’s quality of life and the waters of the Pensacola Bay basin through community participation and coordination with local governments, citizens, academia, and the private sector. The WFRPC serves as staff to the BARC (WFRPC 2016b).
B-11 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT University of Florida Institute of Food and Agricultural Sciences Extension (UF-IFAS)
The UF/IFAS is a federal-state-county partnership that focuses on research, teaching, and extension to “develop knowledge in agriculture, human and natural resources, and the life sciences, and enhance and sustain the quality of human life by making that information accessible.”
Many UF/IFAS programs and partnerships help protect water resources across the Pensacola Bay watershed and the state of Florida. Such programs and partnerships include the Fisheries and Aquatic Sciences and Marine Sciences Program, the Aquatic and Invasive Plants Center, the Florida Cooperative Fish and Wildlife Research Unit., the Florida Partnership for Water, Agriculture and Community Sustainability, the Natural Resources Leadership Institute, the Wetland Biogeochemistry Laboratory, and the Shellfish Aquaculture Extension among others.
To promote environmentally sound forestry practices, the UF/IFAS offers the voluntary Forest Stewardship Program, which seeks to help private landowners develop a plan to increase the economic value of their forestland while maintaining its environmental integrity (UF-IFAS 2016b). The Extension also works with farmers and property owners across the state to minimize the need for commercial pesticides and fertilizers, through environmentally friendly BMPs.
Local Government Planning Initiatives
Escambia County Land Development Code and Comprehensive Plan for Wetlands and Environmentally Sensitive Lands – Escambia County’s land development regulations limit adverse impacts and discourage development that may adversely affect wetlands and other sensitive areas. The county implemented a wetland ordinance in 2001 that provides protection standards, presents local permitting and mitigation programs, and establishes an environmental lands trust fund (Escambia County 2014).
Santa Rosa County Land Development Code for Environmentally Sensitive Lands – The County’s land development regulations add protection of environmentally sensitive lands. Sensitive lands recognized include aquatic preserves, OFWs, functioning wetlands, fish and marine habitats, habitats of threatened or endangered plants and animals, and potable wells (Santa Rosa County 2016).
Escambia County Wellhead Protection Ordinance – Escambia County’s wellhead protection zone ordinance restricts or prohibits certain land use activities within buffers around protected wells or within the seven- or 20-year time of travel contours around protected wells (FDEP 2007).
Okaloosa County Wellhead Protection Ordinance – Okaloosa County’s wellhead protection ordinance prohibits certain land use activities within a 200-foot radius buffer of public supply water wells with a permitted capacity of 100,000 gallons or more per day (FDEP 2007).
Walton County Wellhead Protection – Walton County’s wellhead protection zone limits land uses in wellhead protection zones and/or aquifer recharge areas, to include protection of a 400-foot radius around public potable water wells (FDEP 2007).
Santa Rosa County Wellhead Protection – Santa Rosa County wellhead protection zones were established for public supply wells, consisting of a 200-foot radius Floridan aquifer wells and a 500-foot radius for sand-and-gravel aquifer wells (FDEP 2007).
East Milton Wellfield Protection Area Zoning Overlay District – Santa Rosa County established an overlay district encompassing almost 51 square miles in the inland sand and gravel aquifer wellfield area (Santa Rosa County 2013).
B-12 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT Other Programs and Initiatives
As described in the preceding section, local governments and organizations are active participants in the restoration projects being or expected to be funded through the RESTORE Act, the NRDA, and the NFWF. These organizations have been longstanding partners in monitoring water quality and environmental health throughout the watershed. They have also been key partners in developing stormwater master plans and retrofit projects to reduce and treat stormwater, as well as building community support for watershed protection through the creation of citizen advisory councils and volunteer organizations.
Numerous citizen or citizen-government groups with a primary interest in protecting or enhancing water resources are active in the Pensacola Bay system. Most organizations have a specific geographic focus at either the watershed or waterbody level. Among local and regional organizations and initiatives are the following:
Bayou Chico Association – The Bayou Chico Association is involved in educating the public, seeking grants, and initiating various projects to promote the restoration and preservation of Bayou Chico. The Association has worked for many years in partnership with local governments and the District to advance efforts to protect and restore Bayou Chico. Bayou Texar Foundation – The mission of the Bayou Texar Foundation is to protect and improve the bayou. Its members have worked with the City of Pensacola to implement a stormwater utility to fund stormwater retrofits. The Foundation has educated its members and other area residents about stormwater runoff and what each citizen can do to improve the water quality of this urban bayou (BTF 2016). Environmental Education Coordination Team (EECT) – A partnership of representatives of more than 20 public and private organizations, as well as individual community members, the EECT was formed to consolidate the efforts of members’ environmental education activities in the community. In 2002, the EECT became a subcommittee on the BARC Technical Advisory Committee (WFRPC 2016b). Pensacola Environmental Advisory Board (EAB) – The Pensacola City Council created this group of appointed citizen volunteers in November 2001 to provide policy advice and recommendations on environmental matters to the City Council and city staff (Pensacola EAB 2016). Escambia County Citizens Environmental Committee – The Escambia County Citizens Environmental Committee provides professional advice, based on citizen input, to Escambia County through its Board of County Commissioners on matters of environmental concern (land, air, and water). The County Administrator appoints one member and each commissioner appoints two members, with their terms running concurrently with that of the commissioner who appointed them. Monthly meetings are open to the public (FDEP 2007). Escambia County Storm-Water Advisory Team – In response to the large flooding event in April 2014, the Storm-Water Advisory Team was created to identify conditions associated with the April 2014 flooding and to assist Escambia County staff. The rainfall caused damage to both public and private stormwater facilities across the county, but mostly in the southern area. A needs assessment and a county- wide stormwater recommendation report were drafted to rank priority drainage projects and provide recommendations for stormwater within Escambia County (Escambia County 2016b). Emerald Coastkeeper – The Emerald Coastkeeper is a part of the Waterkeeper Alliance, working to protect and restore area waterbodies. The Emerald Coastkeeper has participated in efforts to restore Carpenter Creek and Bayou Texar, among other activities. Partnership for Environmental Research and Community Environmental Health (PERCH) – This group, funded by federal appropriation grants, was formed to provide input to the University of West Florida
B-13 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT regarding environmental health studies, and investigate questions pertaining to environmental pollution and how it may affect human health (University of West Florida PERCH 2016). Gulf Coastal Plain Ecosystem Partnership – Formed in 1996, this is a cooperative environmental management partnership between the NWFWMD, Blackwater River State Forest, Conecuh National Forest, Nokuse Plantation, Eglin AFB, International Paper, FDEP, and TNC. The Partnership’s initial focus was to restore and protect longleaf pine habitat. The partners currently manage more than 950,000 acres in northwest Florida and southern Alabama, including the Pensacola Bay system. The partnership provides a collaborative approach to preservation and management of natural lands through a set of land management principles directed at ecosystem preservation including prescribed burning, recovering listed species, restoring aquatic habitat, providing public outreach, and sharing and exchanging relevant information and technology on new land management and protection techniques. Through collaboration and the pooling of resources, the partners are able to leverage the purchase of additional conservation lands (The Longleaf Alliance 2016). Ecosystem Restoration Support Organization, Inc. – Formed in 1998, this 501(c)(3) citizen support organization provides financial and volunteer support for the FDEP’s Northwest District Ecosystem Restoration Section. Fundraising and grant-writing efforts have provided over $1 million to Project GreenShores and the FDEP’s seagrass tissue culture lab and greenhouses (FDEP 2016f).
B-14 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT Appendix C Geology and Soils in the Pensacola Bay System
The Pensacola Bay system encompasses two localized physiographic regions in Florida: the Western Highlands subdivision of the Northern Highlands and the Gulf Coastal Lowlands. Both physiographic regions exhibit unique geology and soils. The Northern Highlands are underlain by the Citronelle formation, ancient delta deposits of clays, clayey sands, and gravel, deposited on limestone bedrock. The Coastal Lowlands are described as a flat, weakly dissected alluvial plain formed by deposition of continental sediments onto a submerged, shallow continental shelf, that were later exposed by sea level subsidence. In the Coastal Lowlands, ancient marine geomorphic features including beach ridges, spits, bars, dunes, and terraces make up the modern topography. Terraces represent wave-cut platforms and depositional features that formed during still sands of the sea.
The area surrounding the Pensacola Bay system is underlain by thin undifferentiated alluvium and Pleistocene terrace deposits that dip southwestward at 30 to 40 feet per mile (Marsh 1966). Stratigraphically, these sediments are underlain by the Pliocene Citronelle Formation and Tertiary beds of sand, silt, and limestone. Three Pleistocene-age marine terraces can be recognized in the area: the Pamlico terrace at 30 feet, the Penholoway terrace at 70 feet, and a seaward sloping upland surface with elevations ranging from 60 to 200 feet. Remnants of these terraces are preserved as upland plateaus, flat-topped hills, and low coastal plains (Marsh 1966).
Santa Rosa Island is a bay barrier bar with a straight seaward margin. The island is approximately half a mile wide with sand dunes that reach elevations of 50 feet above sea level. Santa Rosa Island also has two backshore terraces likely formed during storm events.
The mineralogy of sediments within Pensacola Bay is controlled by erosion throughout the watershed, which has taken place since the Pleistocene Epoch. During the Pleistocene, the Citronelle deposits were reworked and intermixed with marine terrace deposits (Marsh 1966). These marine deposits, as well as Miocene and Pleistocene terrace deposits, are now actively eroding. Because the watershed’s streams pass largely through Neogene Coastal Plain formations, the bay's sediments consist almost entirely of sand, silt, and clay eroded from these older units (George 1988).
The mineral suite for the Pensacola Bay system is made up of largely reworked, stable, heavy minerals dominated by zircon, tourmaline, staurolite, and kyanite. Unstable heavy minerals, such as hornblende, garnet, pyroxene, and epidote are lacking. Clay mineral analyses indicate that the Escambia River carries mainly kaolinite, with lesser amounts of montmorillonite, vermiculite, illite, and gibbsite (Isphording et al. 1989). The deposition of sediments in the Pensacola Bay system has significantly changed over recent time. Borings collected during construction of local bridges generally indicate a vegetative "muck” layer in places as deep as 60 feet with cleaner fine to coarse sands below. These deposits are evidence of plant growth at a lower stand of sea level (approximately 6,000 years ago).
The changes in the sedimentary regime of the system are primarily due to the geologically recent rise in sea level. The presence of silty clays, similar to the central bay floor sediment today, suggests that the present sediments were deposited on bay•lagoon deposits behind late Pleistocene barrier islands further offshore.
Soils within the watershed have been used extensively for crop production, silviculture, and pastureland. Along with being a valuable agricultural resource, soils also protect water quality by absorbing runoff, store soil organic carbon, and help mitigate flooding. The following soils are found in the Florida portion of the watershed:
C-1 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Ultisols – Ultisols are intensely-weathered soils of warm and humid climates, and are usually formed on older geologic formations in parent material that is already extensively weathered (i.e., upland areas of the watershed). They are generally low in natural fertility and high in soil acidity, but contain subsurface clay accumulations that give them a high nutrient retention capacity. In the Pensacola Bay watershed, ultisols form in the majority of non-coastal, interior locations where the landscape has been relatively stable over recent geologic time (Collins 2010). Ultisols are the primary agricultural and silvicultural soils of the watershed, as their high clay content contributes to nutrient and water retention, when properly managed and are found extensively in the northern reaches of the entire watershed.
Entisols – Entisols are young soils that show little development, have no diagnostic horizons, and are largely unaltered from their parent material, which can be unconsolidated sediment or rock (USDA 2014). Entisols are found in the floodplain of the Escambia River and on Santa Rosa Sound where surficial processes are active (Collins 2010).
Spodosols – Spodosols are sandy, acidic soils, often found in cool, moist climates such as coastal conifer forests (USDA 2014). They are easily identified by their strikingly-colored horizons, which form as a result of leaching and accumulation processes. Spodosols can be found throughout the coastal portion of the watershed, particularly on the Fairpoint Peninsula, along the Blackwater and Yellow rivers near Blackwater Bay, and throughout the Garcon Point WMA (Collins 2010). The presence of spodosols usually indicates an area that was historically dominated by a pine over-story.
Inceptisols – Inceptisols are described as soils in the beginning stages of soil profile development, as the differences between soil horizons are just beginning to appear in the form of color variation due to accumulations of small amounts of clay, salts, and organic material. Inceptisols occur predominantly along the floodplains of the watershed’s various rivers and tributaries, as well as on Santa Rosa Sound and the tip of Garcon Point (Collins 2010).
Histosols – Histosols are described as soils without permafrost and predominantly composed of organic material in various stages of decomposition. These soils are usually saturated, resulting in anaerobic conditions, slower rates of decomposition, and increased organic matter accumulation. Histosols generally consist of at least half organic materials and are common in wetlands (USDA 2014). Histosols in the watershed occur along the eastern coast of East Bay, along the Escambia River, and along East River near Holley (Collins 2010; USDA 2014). Histosols cover approximately 6,155 square miles in the state of Florida and store more organic carbon than any other soil type (Kolka et al. 2016; Vasques et al. 2010). Drainage of wetland areas and the associated decomposition of organic matter stored in histosols is a well-documented source of atmospheric carbon dioxide and methane.

D-10 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT Appendix E Habitats and Natural Communities
The FNAI defines a natural community as a distinct and recurring assemblage of populations of plants, animals, fungi, and microorganisms naturally associated with each other and their physical environment. Based on GIS analysis, there are 31 unique natural communities recognized by the FNAI within the Pensacola Bay watershed (FNAI 2010). Habitats and Natural Communities were identified using the 2010 Florida Land Use, Cover and Forms Classification System (FLUCFS) data from the NWFWMD as well as the 2004-2013 Statewide Land Use Land Cover datasets created by the five (5) Water Management Districts in Florida. Data were modified and refined based on aerial photograph signatures and field observations. Below are community descriptions (excerpts from FNAI 2010) with site-specific information about many of the communities in the watershed. Upland Communities Bluff is a habitat characterized as a steep slope with rock, sand, and/or clay substrate that supports sparse grasses, herbs, and shrubs. Bluff This community type can be found along the watersheds’ major rivers. In Okaloosa County, the Yellow River cuts through the Western Highlands province, characterized in some areas by bluffs as high as 40 feet (Gardner 1991). Mesic flatwoods can be found on the flat sandy terraces left behind by Plio-Pleistocene high sea level stands. Mesic flatwoods consist of an open canopy of tall pines (commonly longleaf pine or slash pine) and a dense, low ground layer of shrubs, grasses (commonly wiregrass), and forbs. The most widespread natural community in Florida, mesic flatwoods are home to many rare plants and animals such as the frosted flatwoods salamander (Ambystoma cingulatum), the reticulated flatwoods salamander (Ambystoma Mesic Flatwoods bishop) the Red-cockaded woodpecker (Leuconotopicus borealis) and many others. Mesic flatwoods require frequent fire (two to four years) and all of its constituent plant species recover rapidly from fire, including many rare and endemic plants. In the Panhandle north of the Cody Scarp, mesic flatwoods occupy relatively small, low-lying areas (FNAI 2010). Within the Pensacola Bay watershed, healthy mesic flatwoods occur in the Elevenmile Creek watershed and Escribano Point. Sandhill communities are characterized by broadly-spaced pine trees with a deciduous oak understory, sparse midstory of deciduous oaks, and a moderate to dense groundcover of grasses, herbs, and low shrubs. Species typical of sandhill communities include longleaf pine (Pinus palustris), turkey oak (Quercus laevis), and wiregrass (Aristida stricta var. beyrichiana). Sandhill is observed Sandhill on crests and slopes of rolling hills and ridges with steep or gentle topography. Sandhill communities are important for aquifer recharge, as sandy soils allow water to infiltrate rapidly, resulting in sandy, dry soil, with little runoff evaporation. Fire is a dominant environmental factor in sandhill ecology and is essential for the conservation of native sandhill flora and fauna (FNAI 2010). Within the Pensacola Bay watershed, exemplary sandhill communities can be found on Eglin AFB. Scrub is a community composed of evergreen shrubs, with or without a canopy of pines, and is found on well-drained, infertile, narrow sandy ridges distributed parallel to the coastline. Signature scrub species include three species of shrubby oaks, Florida Scrub rosemary (Ceratiola ericoides), and sand pine (Pinus clausa), which may occur with or without a canopy of pines. Scrub is characterized by burn intervals of five to 40 years, depending on the dominant vegetation. This community type can be found in the Gulf Islands National Seashore.
E-1 Pensacola Bay System SWIM Plan Northwest Florida Water Management District August 10, 2017 DRAFT
Scrubby flatwoods have an open canopy of widely-spaced pine trees (commonly longleaf or slash pines) and a low, shrubby understory which differ structurally from scrub communities in the respect that scrub flatwoods lack continuous shrubby oak cover. Understory vegetation consists largely of scrub oaks and saw palmetto, often interspersed with barren areas of exposed sand. Scrubby flatwoods occur on slight rises within mesic flatwoods and in transitional areas between scrub and mesic flatwoods. Scrubby Flatwoods Scrubby flatwoods are inhabited by several rare plant and animal species including the Florida mouse (Podomys floridanus), Florida scrub-jay (Aphelocoma coerulescens) (Peninsular Florida only), gopher tortoise (Gopherus polyphemus), the Florida gopher frog (Rana capito), goldenaster (Chrysopsis floridana), and large-plumed beaksedge (Rhynchospora megaplumosa) (FNAI 2010). Within the Pensacola Bay watershed, scrubby flatwood communities can be found in the Gulf Islands National Seashore. Slope forest is a well-developed, highly diverse, dense canopy forest of upland hardwoods that occurs on steep slopes, bluffs, and in sheltered ravines. In slope forests, high density and diversity is driven by competition for space, water, sunlight, and nutrients. The Slope Forest combination of densely shaded slopes and cool, moist microclimates produces conditions that are conducive for the growth of many plant species that are more typical of the Piedmont and Southern Appalachian Mountains (FNAI 2010). Terrestrial caves are cavities below the surface that lack standing water. These caves develop in areas of karst topography; water moves through underlying limestone, dissolving it and creating fissures and caverns. Most caves have stable internal environments with temperature and humidity levels remaining fairly constant. In areas where light is present, some plants may exist, although Terrestrial Caves these are mostly limited to mosses, liverworts, ferns, and algae. Subterranean natural communities such as terrestrial caves are extremely fragile because the fauna they support are adapted to stable environments and do not tolerate environmental changes (FNAI 2010). Upland hardwood forests are described as having a well-developed, closed-canopy dominated by deciduous hardwood trees such as southern magnolia (Magnolia grandiflora), pignut hickory (Carya glabra), sweetgum (Liquidambar styraciflua), Florida maple (Acer saccharum ssp. floridanum), live oak (Quercus virginiana), American beech (Fagus grandifolia), white oak (Q. alba), and Upland Hardwood spruce pine (Pinus glabra), and others. This community occurs on mesic soils in areas sheltered from fire, on slopes above river Forests floodplains, in smaller areas on the sides of sinkholes, and occasionally on rises within floodplains. It typically supports a diversity of shade-tolerant shrubs, and a sparse groundcover. Upland hardwoods occur throughout the Florida Panhandle and can be found in upper portions of the watershed. Wet flatwoods are pine forests with a sparse or absent midstory. The typically dense groundcover of hydrophytic grasses, herbs, and low shrubs occurring in wet flatwoods can vary depending on the fire history of the system. Wet flatwoods occur in the ecotones between mesic flatwoods and shrub bogs, wet prairies, dome swamps, or strand swamps and are common throughout most of Wet Flatwoods Florida. Wet flatwoods also occur in broad, low flatlands, frequently within a mosaic of other communities. Wet Flatwoods often occupy large areas of relatively inaccessible land, providing suitable habitat for the Florida black bear (Ursus americanus floridanus) as well as a host of rare and endemic plant species (FNAI 2010). This community type is found throughout Eglin AFB. Xeric hammock is an evergreen forest typically dominated by sand live oak (Quercus geminata), found on deep, fine sand substrate, where fire exclusion allows for the establishment of an oak canopy. In these areas, xeric hammock can form extensive stands or as small patches within or near sandhill or scrub. These forests are also found on high islands within flatwoods or less commonly on a high, well-drained ridge within a floodplain where fire-exclusion allows for the establishment of an oak canopy. Xeric hammocks Xeric Hammock are inhabited by several rare animals including the gopher frog (Rana capito), gopher tortoise (Gopherus polyphemus), eastern diamondback rattlesnake (Crotalus adamanteus), and the Florida pine snake (Pituophismelanoleucus mugitus). Xeric hammock is most common in the central peninsula of Florida and is less common north of the Cody Scarp where clay-rich soils create mesic conditions (FNAI 2010). This community type can be found throughout Eglin AFB.

Coastal Communities The beach is the immediate shoreline area of the Gulf of Mexico and consists of white quartz sand. It has few plants, except along the extreme inner edge at the base of the dunes. Organic marine debris, including seaweed and driftwood, typically form a wrack line Beach on the shore. The upper beach area at the base of the foredune is an unstable habitat and is continually re-colonized by annuals, trailing species, and salt-tolerant grasses (FNAI 2010). Beach habitat is found along the entire Gulf front, especially at tidal passes, and some bay front shorelines in the watershed. The beach dune community includes seaward dunes that have been shaped by wind and water movement. This community is composed primarily of herbaceous plants such as pioneer grasses and forbs, many are coastal specialists. The vegetated upper beach and foredune are often sparsely covered by plants adapted to withstand the stresses of wind, water, and salt spray, or to rapidly Beach Dune recolonize after destruction. Many rare shorebirds use the Florida Panhandle’s beach dunes for nesting. This community is also a major nesting area for loggerhead, green, Kemp’s Ridley, and leatherback sea turtles. Beach dune habitat can be found south of the Santa Rosa Sound and the Gulf Islands National Seashore. Coastal grassland, found primarily on broad barrier islands and capes, is a predominantly herbaceous community found in the drier portion of the transition zone between the beach dune and coastal strand or maritime hammock communities. Several rare animals use coastal grasslands for foraging and nesting, including neo-tropical migratory birds and the Santa Rosa beach mouse (Peromyscus Coastal Grasslands polionotus leucocephalus), one of four rare subspecies of beach mouse along the Florida Panhandle coast. Coastal grassland can form from two major processes: the seaward build-up of a barrier island, which protects inland ridges from sand burial and salt spray, or the development of a new foredune ridge, which protects the previously overwashed area behind it (FNAI 2010). This community type can be found throughout Eglin AFB and the Gulf Islands National Seashore. Coastal strand is an evergreen shrub community growing on stabilized coastal dunes, often with a smooth canopy due to pruning by wind and salt spray. It usually develops as a band between dunes dominated by sea oats along the immediate coast, and maritime Coastal Strand hammock, scrub, or mangrove swamp (in peninsular Florida) communities further inland. This community is very rare on the Florida Panhandle coast where the transition zone is occupied by scrub or coastal grassland communities (FNAI 2010). This community type can be found in the Gulf Islands National Seashore. Maritime hammock is a predominantly evergreen hardwood forest that occurs on deep well-drained sandy soils or sandy soils mixed with shell fragments. Maritime hammock forests grow on stabilized coastal dunes at various distances from the shoreline. Maritime Maritime Hammock hammocks provide migrating songbirds with crucial resting and foraging areas on their fall and spring migrations to and from the tropics. On the Florida Panhandle coast, maritime hammock is found only in isolated pockets where shell is mixed with sandy substrate (FNAI 2010). Within the Pensacola Bay watershed, this community type can be found in the Pensacola NAS. Transitional and Wetland Communities Basin marshes, unlike depression marshes, are marshes that lack a fire-maintained matrix community and rather occur in relative isolation as larger landscape features. Basin marshes are regularly inundated freshwater from local rainfall, as they occur around fluctuating shorelines, on former “disappearing” lake bottoms, and at the bead of broad, low basins marking former embayments of Basin Marsh the last high-sea level stand. Species composition is heterogeneous both within and between marshes and generally includes submerged, floating, and emergent vegetation with intermittent shrubby patches. Common species include maidencane (Panicum hemitomon), sawgrass (Cladium sp.), bulltongue arrowhead (Sagittaria lancifolia), pickerelweed (Pontederia cordata), and cordgrass (Spartina sp.) (FNAI 2010).

Basin swamp is a wetland vegetated with hydrophytic trees, commonly including pond cypress (Taxodium ascendens) and swamp tupelo (Nyssa sylvatica var. biflora) and shrubs that can withstand an extended hydro-period. Basin swamps are characterized by highly variable species composition and are expressed in a variety of shapes and sizes due to their occurrence in a variety of landscape positions including old lake beds or river basins, or ancient coastal swales and lagoons that existed during higher sea Basin Swamp levels. Basin swamps can also exist around lakes and are sometimes headwater sources for major rivers. Many basin swamps have been heavily harvested and undergone significant hydrological changes due to the conversion of adjacent uplands to agricultural and silvicultural lands (FNAI 2010). An exemplary basin swamp community is located in the Blackwater River State Park near the entrance station (FDEP 2016a). Baygall is an evergreen-forested wetland dominated by bay species including loblolly bay (Gordonia lasianthus), sweetbay (Magnolia virginiana), and/or swamp bay (Persea palustris). This community can be found on wet soils at the base of slopes or in depressions; on the edges of floodplains; and in stagnant drainages. Baygalls are not generally influenced by flowing water, but may Baygall be drained by small blackwater streams. Most baygalls are small; however, some form large, mature forests, called “bay swamps.” The dominance of evergreen bay trees rather than a mixture of deciduous and evergreen species can be used to distinguish baygall from other forested wetlands (FNAI 2010). An exemplary baygall community is located in the Blackwater River State Park. Bog habitat typically includes areas of saturated substrates, often deep peat, and acidic conditions, with the dominant vegetation Bog consisting of sedges and grasses. Bog habitat is often surrounded by a transition zone of trees and shrubs between the bog and upland area (FNAI 2010). In the Pensacola Bay watershed, this community type can be found along many of the watersheds’ major rivers. Coastal interdunal swales are marshes, moist grasslands, dense shrublands, or damp flats in linear depressions that occur between successive dune ridges as sandy barrier islands, capes, or beach plains. Dominant species tend to vary based on local hydrology, substrate, and the age of the swale, but common species include sawgrass (Cladium sp.), hairawn muhly (Muhlenbergia capillaris), Coastal Interdunal broomsedge (Andropogon virginicus), seashore paspalum (Paspalum vaginatum), sand cordgrass (Spartina bakeri), and saltmeadow Swales cordgrass (Spartina patens). For example, hurricanes and large storm events can flood swales with saltwater, after which they become colonized, often temporarily, by more salt-tolerant species. Saltwater intrusion and increased sand movement after storm events can reset successional processes of interdunal swale communities (FNAI 2010). This community type can be found in the Gulf Islands National Seashore. Dome swamp is an isolated, forested, and usually small depression wetland consisting of predominantly pond cypress (Taxodium ascendens) and/or swamp tupelo (Nyssa sylvatica var. biflora). This community occurs within a fire-maintained community such as mesic flatwoods and commonly occupies depressions over a perched water table. Smaller trees grow on the outer edge of the swamp where the water is shallow, while taller trees grow deeper in the swamp interior creating the characteristic dome shape. Shrubs are typically sparse to moderate, but dome swamps with high fire frequencies or fire exclusion, the shrub layer may be absent. Many dome swamps form when poor surface drainage causes the dissolution of limestone bedrock, creating depressions which fill in with Dome Swamp peat or marl. Surficial runoff from the surrounding uplands supplies much of the water within dome swamps. Consequently, water levels in these communities fluctuate naturally with seasonal rainfall changes. Dome swamps may also be connected directly to the aquifer, where groundwater influences the hydrological regime. Thus, dome swamps can function as reservoirs that recharge the aquifer. Logging, nutrient enrichment, pollution from agricultural runoff, ditching, impoundment, and invasive exotic species invasion have degraded dome swamps. Some dome swamps have been used as treatment areas for secondarily-treated wastewater (FNAI 2010).

Hydric hammock is an evergreen hardwood and/or palm forest with a variable understory typically dominated by palms and ferns. This community occurs on moist soils, often with limestone very near the surface. While species composition varies, the community generally has a closed-canopy of oaks and palms, an open understory, and a sparse to a moderate groundcover of grasses and ferns. Hydric Hammock Hydric hammock occurs on low, flat, wet sites where limestone may be near the surface and soil moisture is kept high mainly by rainfall accumulation on poorly-drained soils. During heavy rains, sheet flow is slowed across the forested-floor of a hammock, resulting in greater absorption into the soil. Hammocks adjacent to salt marshes protect inland areas from damage during hurricanes and major storms (FNAI 2010). This community type is found on in the Pensacola NAS. Floodplain swamp is a closed-canopy forest community of hydrophytic trees such as bald cypress (Taxodium distichum), water tupelo (Nyssa aquatica), swamp tupelo (N. sylvatica var. biflora), or ogeechee tupelo (N. ogeche). Floodplain swamp occurs on frequently- or permanently-flooded hydric soils adjacent to stream and river channels and in depressions and oxbows within the floodplain. The understory and groundcover are sparse in floodplain swamps, which can also occur within a complex mosaic of communities including alluvial forest, bottomland forest, and baygall. As rivers meander, they create oxbows and back swamps that are important breeding grounds for fish when high water connects them to the river. Floodplain swamp communities provide important wildlife habitat, contribute to flood attenuation, and help protect the overall water quality of streams and rivers. These Floodplain Swamp communities may also transform nutrients or act as a nutrient sink depending on local conditions. This makes floodplain swamps useful for the disposal of partially-treated wastewater. Artificial impoundments on rivers can severely limit the seasonal flooding effects that maintain healthy floodplain systems; particularly, the stabilization of alluvial deposits and the flushing of detritus (FNAI 2010). Floodplain swamp communities are distributed along most creeks and streams within the watershed, particularly along the Yellow, Blackwater, and Escambia rivers. Exemplary sites include the floodplain swamps within the Yellow River Marsh Aquatic Preserve (Gardner 1991). Floodplain swamp occurs along both sides of the Backwater River in the Blackwater River State Park from the edge of the river to about 40 feet in elevation (FDEP 2016a). Seepage slope is an open, grass sedge-dominated community consisting of wiregrass (Aristida stricta), toothache grass (Ctenium aromaticum), pitcher plants, plumed beaksedge (Rhynchospora plumose), flattened pipewort (Eriocaulon compressum), and woolly huckleberry (Gaylussacia mosieri). Seepage slopes are kept continuously moist by groundwater seepage. This community occurs in Seepage Slope topographically variable areas, with 30- to 50-foot elevational gradients, frequently bordered by well-drained sandhill or upland pine communities. The soil is often soft and mucky underfoot, in contrast to the firm texture of the bordering sandhill and upland pine soils. Seepage slopes range from the Alabama border eastward to Calhoun County in the inland portions of the Florida Panhandle. Within the Pensacola Bay watershed, seepage slopes can be found throughout Eglin AFB. Wet prairie is an herbaceous community usually occurring on acidic, continuously wet, but not inundated, soils. This community can be found on somewhat flat or gentle slopes between lower lying depression marshes, shrub bogs, or dome swamps or on slightly higher wet or mesic flatwoods. Wet prairies in northern Florida are some of the most diverse communities in the U.S., with an Wet Prairie average of over 20 species per square meter in some places and over 100 total species in any given stand. The Panhandle is a hotspot for rare plants of the wet prairie community with 25 out of the 30 rare species found in this community; 12 of these are endemic to the Panhandle (FNAI 2010). This community type is found along the watershed’s major rivers and Eglin AFB.

Aquatic Communities Blackwater streams are perennial or intermittent seasonal watercourses laden with tannins (natural organic chemicals), particulates, and dissolved organic matter and iron. These dissolved materials result from the streams’ origins in extensive wetlands with organic soils that collect rainfall and discharge it slowly to the stream. The dark-colored water reduces light penetration, inhibits photosynthesis, and prevents the growth of submerged aquatic plants. Blackwater streams are frequently underlain by limestones and Blackwater Streams have sandy bottoms overlain by organics that have settled out of suspension. Blackwater streams are the most widely distributed and numerous riverine systems in the southeast Coastal Plain (FNAI 2010) and found draining into most creeks, streams and bayous in the watershed. Many of the watershed’s smaller tributaries are true blackwater streams, including several streams that traverse the Blackwater River State Park. Seepage streams may be perennial or intermittent seasonal as they originate from shallow groundwater percolating through sandy upland soils. Seepage streams are small magnitude features, and unlike other stream communities in Florida, they lack a deep aquifer water source and extensive swamp lowlands surrounding their head waters. Seepage streams are generally sheltered by a dense overstory of broad-leaved hardwoods which block out most sunlight. Filamentous green algae occur sporadically within the stream, while vegetation at the water’s edge may include mosses, ferns and liverworts. Seepage streams are often associated with seepage Seepage Streams slope and slope forest communities near their head waters, and bottomland forest, alluvial forest and floodplain swamp communities near their mouths. The waters of seepage streams is filtered by percolation through deep soils which slows the release of rainwater and buffers temperature extremes, creating low flow rates of clear, cool, unpolluted water. Seepage streams are generally confined to areas where topographic relief is pronounced such as northern Florida (FNAI 2010). Within the Pensacola Bay watershed, seepage streams are found along the watersheds’ major rivers and Eglin AFB. Seepage streams run throughout the Blackwater River State Park. The Hynote Branch is one example of a seepage stream in the park that is good to excellent condition (FDEP 2016a). Estuarine and Marine Communities Salt marsh is a largely herbaceous tidal zone community commonly consisting of saltmarsh cordgrass (Spartina alterniflora), which dominates the seaward edge, and needle rush (Juncus roemerianus), which dominates higher, less frequently flooded areas. Salt marshes form where the coastal zone is protected from large waves, either by the topography of the shoreline, a barrier island, or by location along a bay or estuary. Salt marshes support a number of rare animals and plants, and provide nesting habitat for migratory Salt Marsh and endemic bird species. Many of Florida’s extensive salt marshes are protected in aquatic preserves, but the loss of marshes and adjacent seagrass beds due to human impacts such as shoreline development, ditching, and pollution and natural stressors, such as sea level rise, have vastly reduced their numbers. Salt marshes are instrumental in attenuating wave energy and protecting shorelines from erosion (FNAI 2010) and are found in the coastal/ estuarine portion of the watershed. Salt marsh communities are common throughout the Pensacola Bay watershed and are particularly extensive at the Yellow River Marsh Aquatic Preserve (Gardner 1991). Seagrass beds consist of expansive stands of submerged aquatic vascular plants including turtlegrass (Thalassia testudinum), manateegrass (Syringodium filiforme), and shoalgrass (Halodule wrightii), which occur predominantly in subtidal zones in clear low- energy coastal waters. Seagrass beds occur on unconsolidated substrates and are highly susceptible to changes in water temperature, salinity, wave-energy, tidal activity, and available light. This natural community supports a wide variety of animal life including Seagrass Beds manatees, marine turtles, and many fish, particularly spotted sea trout (Cynoscion nebulosus), spot (Micropogonias undulates), sheepshead, (Archosargus probatocephalus), and redfish (Sciaenops ocellatus). Pollution, particularly sedimentation and wastewater/sewage, have led to the widespread loss of seagrasses in nearly every bay in the Florida Panhandle (FNAI 2010). Seagrass beds have historically been widespread throughout the Pensacola Bay system, but declined substantially in the mid-1900s due to poor water quality.

Oyster/mollusk reef consists of expansive concentrations of sessile mollusks, which settle and develop on consolidated substrates including rock, limestone, wood, and other mollusk shells. These communities occur in both the intertidal and subtidal zones to a depth of 40 feet. In Florida, the American oyster (Crassostrea virginica) dominates mollusk reef communities, but other organisms Oyster/Mollusk Reef including species of sponge, anemones, mussels, the burrowing sponge anemones, mussels, clams, barnacles, crabs, amphipods, and starfish live among or within the reef itself. Mollusks are filter-feeders that remove toxins from polluted waters and improve overall water quality (FNAI 2010). Unconsolidated (marine) substrate consists of coralgal, marl, mud, mud/sand, sand or shell deposited in expansive, open areas of subtidal, intertidal, and supratidal zones. Unconsolidated substrates support large populations of tube worms, sand dollars, mollusks, isopods, amphipods, burrowing shrimp, and an assortment of crabs, but lack dense populations of sessile plant and animal species. Unconsolidated substrates are an important feeding ground for bottom-feeding fish, shorebirds, and invertebrates. These areas also Unconsolidated grade into a variety of other natural communities, making them the foundation for the development of other marine and estuarine (Marine) Substrate habitats. Unconsolidated substrate communities are found throughout the estuarine and riverine portions of the watershed. They are susceptible to many types of disturbances including vehicle traffic, low DO levels, as well as the accumulation of metals, oils, and pesticides in the sediment (FNAI 2010). Unconsolidated (marine) substrate can be found throughout Escambia Bay, Pensacola Bay, and Big Lagoon. Source: FNAI 2010.
